What Is PHP? PHP is a server-side scripting language primarily used for web development and DevOps tools. Its seamless integration with HTML helps make websites more dynamic and interactive. Despite being over 25 years old, PHP is still employed on approximately 80% of all websites. PHP's strengths include its ease of use and access to effective frameworks. Additionally, its platform independence ensures compatibility with any operating system or web browser. Back-end and full-stack developers widely employ PHP because of its versatility. As an open-source language, there are abundant online resources and a thriving community available for those interested in learning the language. Companies such as Slack, Wikipedia, Tumblr, Etsy, etc., have a wide application of PHP. Benefits of PHP Low development costs Highly adaptable for web app development Comprehensive learning resources for developers worldwide Disadvantages of PHP Vulnerable due to open-source text files Inconsistent documentation What Is Java? Java is a compiled, general-purpose programming language that follows the object-oriented paradigm. It’s mostly used for developing web and mobile enterprise-level applications. Java has a powerful presence in various domains, such as game consoles, mobile phones, data centers, and scientific supercomputers, owing to its computational power. Java is also a computing platform based on Java Virtual Machine and Java API. Virtual machines enable efficient operations. PHP rarely accompanies the words "computing platform", but it also has a virtual machine (Php 7 Zend Virtual Machine or Facebook's HHVM). In Java, compiled code is stored separately and requires recompilation in the JVM. Conversely, Zend's opcache module caches the compiled version of PHP, eliminating the need for recompilation in each execution. Java's popularity is clear from the fact that it was ranked as the second most popular programming language worldwide, according to The PYPL Popularity of Programming Language Index. As a result, a variety of job positions and career paths demand proficiency in Java. Lots of learning resources and online support make it a great language to start with. Such enterprises as Google, eBay, Amazon, Uber, Netflix, Instagram, etc., use Java. Benefits of Java Highly secure Offers both automatic and advanced manual memory management for large-scale enterprise applications If you're looking to hire a dedicated Java developer, you may discover that it's easy to find highly skilled programmers in the expansive talent pool available Disadvantages of Java Development can be costly as not all Java versions are free Likely poor performance during startup Typically longer code Need guidance selecting an appropriate programming language for your project? Or decided to hire a dedicated Java developer? Talk to our technical expert. PHP vs. Java: What Is the Difference? Speed Of Coding PHP's latest versions enable developers to speed up application development while simultaneously reducing memory usage. Java's ability to manage and process many instruction sequences with multiple threads allows for faster and more efficient enterprise application development. Verdict: PHP Performance While PHP requires time to interpret each requested bytecode, the latest versions of PHP support caching, which help mitigate this issue. On the other hand, Java's precompiled nature and optimization techniques give it an edge in performance over PHP, making it a more high-performing language. Verdict: Java Page Loading Speed Page load speed is a crucial factor for websites, with users typically expecting pages to load within 2-3 seconds. Slow loading times may cause users to leave. Java-based websites are relatively rare, and this is not only because they tend to be slower but also because they consume more memory to run, making them more expensive. Consequently, for sites handling millions of requests, Java might not be a cost-effective choice. In contrast, PHP loads pages faster as it requires fewer resources compared to the Java Server Pages (JSP) engine. Verdict: PHP Stability Software stability hinges on finding the right balance in code length. Code should be succinct for readability and maintainability, yet comprehensive enough to include essential logic, error handling, and documentation for stability. Java, with its well-crafted and extensive code, typically provides a higher level of stability. In contrast, PHP, which often employs shorter code, may not offer the same level of stability. Consequently, numerous FinTech companies and banks prefer Java for its track record of fewer crashes, rendering it more stable than PHP. Verdict: Java Cost of Development Typically, the cost of development isn't the major factor when choosing a programming language. It's more crucial to evaluate the current and medium-term tasks at hand. Long-term plans are often unnecessary, even for large projects, as the microservice architecture can effectively manage the task distribution. However, for businesses prioritizing cost-efficient app development, PHP-based applications often edge out Java. While Java might require a higher investment of time and resources, PHP offers a more budget-friendly alternative. The widespread use of PHP makes it easier to find and hire proficient developers. Additionally, PHP developers usually command lower salaries than their Java counterparts, making PHP development more cost-effective. PHP developer salary in the US averages 63,087 $/yr. Source: payscale.com/research/US/Job=PHP_Developer/Salary US Java developer salary averages $73,540/yr. Source: payscale.com/research/US/Job=Java_Developer/Salary Verdict: Remember to base your decision on the project's needs, not just the budget at hand. Statically Typed vs. Dynamically Typed Java is a statically typed language, meaning that the variables have a fixed type set at the time of design. Java's static typing enables the detection of errors at the early stages of the Systems Development Life Cycle process. Unlike Java, PHP does not require a fixed type for variables. You can employ strings, numbers, arrays, objects, or even functions with no declaration of their type beforehand. Verdict: Java Developer Tools PHP and Java both have a vast selection of IDEs, testing and debugging tools, documentation, security, and performance monitoring products available. Major software companies, smaller teams, and individual developers who cater to specific niches created these tools. Some of the well-known developer tools for PHP include IDEs (PHPStorm, Zend Studio, Eclipse), testing and debugging tools (PHPUnit, Selenium, Xdebug), security (RIPS, Securimage), performance monitoring (Retrace, New Relic APM, AppOptics). Some of the most used tools and products used by Java developers include IDEs (IntelliJ IDEA, Eclipse, NetBeans, BlueJ, JDeveloper), testing and debugging tools (JUnit, JBehave, Serenity, Selenium, TestNG), quality control (SonarCube, Embold), performance monitoring (Java VisualVM, Oracle Java Mission Control, NetBeans Profiler). Verdict: Both Popularity Java is currently more popular than PHP. Hiring requests for Java developers are in high demand, while those for PHP developers rank far lower. In terms of developers' preferences, 45.75% prefer to continue with Java, while only 41.6% prefer to continue with PHP. Therefore, Java is more popular than PHP. According to the “Developer Survey Results 2022”, which was conducted by StackOverflow among over ninety thousand developers from all over the world, Java is used more often compared to PHP. Source: https://survey.stackoverflow.co/2022/#most-popular-technologies-language Java is the second most-used language on GitHub. Source: octoverse.github.com Verdict: Java Talent Pool The quantity of Java developers is greater than that of experienced PHP developers, with an approximate 38.4% of developers using Java and 25.8% opting for PHP. Thus, Java boasts a more promising talent pool than PHP. Verdict: Java PHP vs. Java: What They Have in Common Object-Oriented Programming Both PHP and Java adhere to the principles of object-oriented programming (OOP). This makes it simple to comprehend and reuse code in other programs for both languages. Greater advantages of object-oriented programming become evident as the project becomes more complex and involves more developers. Using OOP reduces the time and cost of software development, maintenance, and support. Open-source programming languages Developers can freely access and use both PHP and Java with no restrictions or associated costs. This makes it simple to customize and distribute PHP and Java-based solutions based on the project's needs. Syntax PHP and Java possess comparable syntax, resulting in a shared foundation with comparable looping structures, class definitions, member functions, data member definitions, and other features. Compiled vs. Interpreted Language Java compiles code, while PHP interprets code. Although compiled and interpreted languages operate differently, various programming languages, such as Java, can function in either capacity. The effectiveness of a language depends on the specific coding task at hand. Compiled languages require the machine to read the entire code block before taking action, enabling the machine to optimize the code by establishing the global context. For instance, if two data pieces are often used together, the machine will physically store them closer in memory. However, this can cause slower code operation and it's hard to pinpoint errors. Interpreted languages involve the machine reading and executing one line of code at a time, starting from the first line. This allows for almost real-time execution, allowing the programmer to see what the code is doing. Interpreted code is easier to debug, and results can be viewed without having to wait for the entire code block to be executed, making it more user-friendly to work with. Memory Although there may be variations in the memory requirements of Java and PHP, these differences are gradually becoming smaller as technology advances. In general, the amount of memory used is more influenced by the framework and the complexity of the code being used, rather than the specific programming language being used. For memory safety, both Java and PHP share some similarities. PHP, being a language that doesn't give developers control over memory management, is relatively secure. Some people widely consider Java one of the safest programming languages in terms of usage and consumption volume. Ease-To-Learn Both PHP and Java are simple to learn. PHP is a popular choice for new programmers. As a result, many developers who are new to programming choose to begin their journey by studying PHP or Java. Don't struggle with the decision alone - reach out to our professionals. We'll help you analyze your idea and guide you to the best choice. Comparing PHP and Java: Use Cases and Developer Insights It's crucial to grasp the specific use cases of Java and PHP to fully appreciate the distinct differences between these two prominent programming languages. Java typically handles complex projects for enterprise-level development, while PHP, being simpler, is often the go-to choice for start-ups. Java serves as a general-purpose language, whereas PHP has evolved primarily to generate dynamic web pages and applications. It is always interesting to hear what other experienced developers think. Here are some quotes we gathered from the web. ‘As a professional Java programmer, I've been trying to understand - why the hate toward Java for modern web applications? I've noticed a trend that out of modern day web startups, a relatively small percentage of them appears to be using Java (compared to Java's overall popularity).’ ‘For smaller applications, Java can be overkill. It shines, however, in larger web applications such as those used by banks and insurance companies.’ ‘Small percentage of modern day web startups use Java’ Now, let's explore some key applications of these languages across the tech industry: Java Use Cases at a Glance: Developing software tools such as IDEs (e.g., NetBeans, IntelliJ Idea, Eclipse, etc.) Designing web servers, including Adobe JRun, Resin, Apache HTTP server, Rimfaxe Web Server (RWS), Apache Tomcat, etc. Creating enterprise-level web and mobile applications Designing various web applications, like shopping carts, online forms, Google Sheets, and Gmail Developing applications for the Android platform PHP Use Cases at a Glance: Designing e-commerce applications, including UberCart, ZenCart, OpenCart, and others Creating dynamic websites, such as MailChimp, iStock Photo, Flickr, Yahoo, and more Creating small web and mobile applications With these broad overviews in mind, let's now delve into a specific sector where both Java and PHP play significant roles – healthcare. In the Healthcare Sector: PHP and Java Healthcare makes use of PHP and Java. The USA-based CIO business magazine reports, “Java is popular for the creation of small to large embedded devices and is often used for the development of remote patient monitoring applications and diverse and robust sensors". According to the CIO magazine, PHP remains popular for healthcare web-based Electronic Health Record management. There is a lot of open-source health software in PHP, for example, OpenEHR. It is rather popular with many reputable healthcare organizations. Java or PHP for Enterprise Apps: Which is Better Java is often the preferred choice for enterprise-level applications, with PHP sometimes being under scrutiny. Yet, the key factor often lies in a developer's skills and knowledge, not the language. Mastering Java can be a longer and more challenging journey, leading to developers typically tackling more complex projects and tasks. Even so, at Belitsoft, you can count on our PHP developers. We take pride in providing our clients with skilled and competent developers, regardless of the technology stack. PHP and Java are both modular platforms with both free and paid licenses. However, Java tends to excel in larger web applications. The latest PHP applications speed up the development process while reducing memory usage. In contrast, Java employs multiple threads for management and processing, making it faster and more efficient. The Java programming language can interact with a variety of systems, including web services, databases, and mainframe back-ends. Both Java and PHP have robust supporting tools. Java frameworks are straightforward to install, well-documented, and effective for monitoring and troubleshooting production applications. However, most times, PHP is considered simpler to use. Java applications often follow the WORA (Write Once Run Anywhere) principle, allowing programmers to develop Java code on one system and run it on any Java-enabled system using the Java Virtual Machine (JVM) as a run-time environment. It's worth noting that PHP offers the same capability. Java does not translate the program directly into hardware-interpreted code. Instead, it converts the code into bytecode (a .class file), which is then interpreted by the Java Virtual Machine (JVM). Once compiled, it generates a bytecode file that can be run on any JVM. Java is an excellent choice for developing robust, reliable, and scalable multi-tiered applications. It has the versatility to create various types of applications, including web applications, native applications, Internet of Things (IoT)-based applications, Android applications, enterprise applications, and more. Future Perspectives The future of programming languages seems to shift towards heightened security and high-level coding that is affordable. While PHP has faster processing speeds than Java in certain projects, the choice between the two depends on the specific project requirements. The expansive language tools, improved security, and increasing Java's popularity are likely to give a slight edge over PHP in the coming future. Java and PHP can work together in two distinct ways. First, it is workable to incorporate PHP into a Java Servlet environment by supplying a SAPI module that interfaces with the Servlet server, leading to an efficient solution. Alternatively, developers can integrate Java support into the PHP environment by utilizing a Java extension. PHP and Java Developers When choosing between Java and PHP, non-technical business decision-makers should keep the following aspects in mind: Select your specialists carefully and give priority to understanding the logic behind each line of code rather than the speed of development. Be cautious about relying on recruiters or consultants who lack hands-on experience in system development and coding. Belitsoft's Experience in Using PHP and Java There are no technical difficulties in creating applications in Java or PHP for a highly experienced programmer. Finding a team of them is much harder. Belitsoft has both PHP and Java teams. Therefore, our company has resources to create PHP-based web applications and Java-based web applications. In each project, our team analyzes the requirements and expected business outcomes to determine the optimal choice between Java and PHP for web development. Our decision-making process considers various factors, including: Evaluating the current infrastructure and technology stack Assessing client's resources for support and maintenance Investigating technology trends in the market niche Considering the solution architecture and complexity Examining predicted website traffic Discovering project needs for a framework or third-party libraries Calculating TCO (Total Cost of Ownership) for different solutions We believe every task has the most suitable tool or combination of tools to accomplish it. For certain projects, the advantages of utilizing Java instead of PHP are apparent due to the extensive size and complexity of the solution or its intended future use. In such cases, we advise our clients to engage Java developers, accompanied by some Quality Assurance specialists and a designated Project Manager, to execute the project successfully. In different scenarios, when selecting between PHP and Java for backend components, we prefer PHP frequently because of its faster development speed, greater comfort for web designers, ease of making modifications, and more affordable project costs.  Dmitry Garbar has managed the PHP teams for Belitsoft since 2004. His team has over 10+ years experience in creating complex and secure applications for different industries including healthcare, backend for web and mobile applications, (Electronic Health Record management application), complex forms for lead generation platforms and SAAS platforms for insurance brokers (INSLY) and much more. We utilize modern approaches and technologies, including microservice architecture, the Laravel framework, and the most recent LTS versions of PHP. However, we can also work with older versions if a client requires customization, migration, or modernization of their legacy software. Microservice architecture promotes scalability and simplifies backend maintenance. It's a contemporary approach that supports the cost-effective development of enterprise-level applications. With Microservices, you can construct your software using a variety of programming languages. Laravel is an outstanding PHP framework known for reducing development time. PHP 8 is one of the most secure and fast versions of PHP currently available. When operating as a Laravel Development Company, our primary focus is on development, customizing and optimizing Laravel-based applications. However, we remain unbiased and prioritize the technology that best meets our client's business needs, whether that's PHP, Java, or another option.

What is Java Java is an object-oriented statically-typed programming language and computing platform. It was released by Sun Microsystems in 1995 (later acquired by Oracle Corporation). Today, most major elements of Java are accessible as open source, and those that do not mostly have open replacements for them. Sun, the original developers of Java, placed much of it under the GNU General Public Licence in 2006. Java is employed in the development of Android apps, server apps, web apps, websites, embedded systems.  It is especially popular in financial software development. What is Kotlin Kotlin is a statically typed programming language that targets the JVM, Android, JavaScript, and Native. Kotlin is open source developed under the Apache 2.0 license. The source code is available on GitHub. The language combines both object-oriented and functional programming features. You can use it in both OO and FP fashion, or blend elements of the two. Kotlin boasts the support of all major Java IDEs including IntelliJ IDEA (the brainchild of JetBrains), Android Studio, Eclipse, and NetBeans. It can be used for most kind of apps, be it server-side, client-side web or Android. Kotlin/Native, that is currently in the pipeline, will provide support for other platforms such as embedded systems, macOS, and iOS. Java to Kotlin story Although Kotlin v1.0 was released only on February 15, 2016, the history of this programming language dates back to 2011. Kotlin was created by JetBrains out of their practical needs. The company had 70% of its products build on Java but started to realize its shortcomings - mainly excessive verbosity. They wanted a language that would be Java-compatible since rewriting everything into a completely new language seemed a no-go option. They started experimenting with Scala but were not satisfied. That is when the concept of a new language, Kotlin, was born. Another motivation behind Kotlin is fairly straightforward: ‘We expect Kotlin to drive the sales of IntelliJ IDEA.’ Dmitry Jemerov, one of the Kotlin blog contributors Java vs Kotlin: Market situation The influence of Java on the development world is huge, which is backed up by the reputable Tiobe Index. As of July 2019, Java has maintained its number one spot compared to July 2018. Kotlin, though still a young language, has made it to the top 50 of the rankings, setting down at number 43. Google  I/O 2017 conference was marked by the promotion of Kotlin to the ranks of its “first-class” programming languages for Android app development. It joined the good old Java and C++. The announcement has fueled up the interest over Kotlin, causing the spectacular growth in its popularity. Source: realm.io ‘Android developers have an official guarantee that the language will be supported, which will lead to further adoption of Kotlin.’ Andrey Breslav, the lead language designer of Kotlin at JetBrains Square, Pinterest, Basecamp, Netflix, Amazon, Uber, Trello, and Twitter have already declared their conversion to Kotlin. AppBrain offers the following numbers for the share of Kotlin apps in Google Play as of July 30, 2019. Java vs Kotlin: Painless transition Kotlin was designed with a strong focus on its interoperability with its elder sibling Java. It means you can translate any Java code into Kotlin or vice versa without changes in their operability. There may be certain features for which you’d prefer Kotlin or some, where Java seems a better option and it’s ok. Since both Kotlin and Java codes compile to JVM bytecode, end users will not be able to tell where the one ends and the other continues. ‘One of the key focuses of Kotlin has been interoperability and seamless support for mixed Java+Kotlin projects.’ Andrey Breslav in his blog post Java vs Kotlin: Verbosity The verbosity of Java has long been its major shortcoming and a source of frustration for the developers. Kotlin is designed to reduce the number of boilerplate code one needs to write.   Source:quiita.com Kotlin conciseness helps to increase a cut in the lines of code by approximately 40 %, according to JetBrains. Real tests show that after converting “App Lock” app from Java into Kotlin, the number of code lines reduces by 30% (from 12,371 lines of Java, to 8,564 lines of Kotlin).   Kotlin also provides a heap of nice-to-use features that Java does not have, like: Extensions, that help to extend a class functionality; Coroutines, aimed at avoiding thread blocking, thus minimizing the risk of errors; Null-safety, that ensures no null references occur, thus reducing the risk of an app going faulty and more. As a result, a more robust and safe code can be written with fewer efforts. The time needed for the amount of the output generation and bugs fixing cuts down. ‘Kotlin isn't revolutionary (with the possible exception of its null-handling) but feels like a very careful amalgamation of some of the best features of other languages. Its approach is very pragmatic and emphasizes interoperability with Java and a lack of surprise.’ Rob Fletcher, a senior software developer at Netflix Mobile app development (Android and iOS) is one of our specialties. Let us know how we can help. Java vs Kotlin: Android Studio 3.0 Support Java implementation in Android ecosystem seems to lag behind the demands of the developers’ community. Though the latest version of Java is SE 10, Android Studio 3.0 and later supports Java 7 and only some of Java 8 features. Thus, developers that are denied the opportunity to embrace the full potential of the latest versions are starting to shift more towards Kotlin. Bearing in mind that Android Studio is based on the JetBrains’ IntelliJ IDEA, it is easy to predict its excellent support for Kotlin. ‘For Android developers, Kotlin support is a chance to use a modern and powerful language, helping solve common headaches such as runtime exceptions and source code verbosity.’ Maxim Shafirov, JetBrains’ CEO, commented in his blog post Java vs Kotlin: Adoption Costs Kotlin is open source, thus you can bring it into play for free. You can start exploring the language simply by translating it via Java-to-Kotlin converter.  Kotlin is compatible with all Java libraries and frameworks, even those that rely on annotation processing. It also perfectly integrates into building tools like Gradle, Maven, Ant, or Kobalt. All you need is to install a Kotlin plugin. ‘Kotlin is easy to get started with and can be gradually introduced into existing projects, which means that your existing skills and technology investments are preserved.’ JetBrains' CEO Maxim Shafirov However, though similar, at their core Java and Kotlin are two different languages. The latter is currently a new language, that means that there is no established equivalent to the sources like Effective Java for best programming practices. So there will be a learning curve for your in-house team to master the Kotlin tricks. Java vs Kotlin: Community support Java is a programming player with more than 2 decades of history. It naturally leads to the unfathomable number of Java projects implemented and an impressive community it gathered. At the time of writing, there were 801,248 repository results for "Java" query at GitHub. The larger the community is, the more likely that someone has already left tips on the issue you are searching for. This, in its turn, makes the development process in a language more easy and enjoyable. Despite the fact Kotlin is gaining more and more traction, its community is still small compared to Java’s. GitHub gave us only 33,182 "Kotlin" tagged results. Therefore, there are few tools to pump up the skills and not so many Kotlin experts to ask (at the time of writing there were 361 job results for "Android Kotlin Developer" www.indeed.com compared to only 2 resumes). Java vs Kotlin: Performance & compile time JetBrains claims that a Kotlin application runs as fast as an equivalent Java one, thanks to very similar bytecode structure. Yet, Kotlin's support for inline functions allows code using lambdas to run even faster than the same code written in Java. The tests conducted show that Java compiles 10-15 % faster for clean builds. However, for incremental compilation, Kotlin shows identical to Java or even slightly better results. Decreased compile time means less unproductive time for a developer. Conclusion Kotlin is not a complete revolution, but rather a pragmatic enhancement of Java. They resemble each other in structure and can peacefully coexist within one project. But because Kotlin is a fresh start to some extent, it adds a variety of state-of-the-art features. Java, however, is like a friend that stood the test of time.

Python Source: https://pixabay.com/ ‘A programming language changes the world.’ Python.org According to Wikipedia, Python was released in 1991 as a high-level language for general-purpose programming. But it actually dates back to 1989. The interest around Python began to rise only around 2000, and today Python is loved for its highly readable code. That is why many programmers believe it's the easiest language to get started with. Why is that? Well, the story starts decades ago. In the 90s, if you wanted a managed, Object Oriented language, there was surprisingly little choice. C# and Java didn't exist, nor did Ruby. We had a sloppy Perl and TCL that had OOP only as an extra feature. Above all, lots of languages were Windows-only like Delphi or Visual Basic. In the meantime, C++ was frightening to beginners, and Smalltalk always felt like a nice idea, but not something you actually wrote software with. And here we go, Python seemed better than everything else what was out there. Java was around since 1995, but it seemed too 'corporate'. In 2000 C# was coming out, but it was, again, Windows only. Source: https://www.reddit.com Today Python is one of the most important and popular languages in the world and is still gaining our attention. Java Source: https://bgr.com/ ‘Java is arguably the most popular programming language as 90% of the Fortune 500 companies heavily use it. Its famous slogan “write once, run anywhere” captures one of the keys that makes Java so valuable — its powerful Java Virtual Machine (JVM), which makes it cross-platform compatible.’ Alexander Petkov, Medium.freecodecamp.org It was 1995 and C++ was the language of choice for building large-scale software systems. It was a powerful object-oriented language, the successor of widely used C. But not only was C++ powerful, it was also quite complicated. Here’s the point where Java was released. Java is a high-level object-oriented language. Initially conceived and developed in 1991 under the name OAK, it was designed for handheld devices and set-top boxes, but due to some circumstances the name was changed to Java and modified the target to the then evolving World Wide Web. So, at the moment, Java is one of the most widely-used languages for developing and delivering content on the web plus developing enterprises applications and Android apps. An estimated 9 million developers use it and more than 3 billion mobile phones run it. #1: History: long ride vs short bite Both languages were developed relatively at the same time, in 1991. But started to draw attention in quite different periods: Java wasn’t really itself back then, and Python just started to open his little pixel-eyes. Nevertheless, they both are actively engaged in making improvements and perfecting the current results: Python. Since the popularity reached a peak, it had given rise to long discussions. Source: https://octoverse.github.com/ 15 most popular languages according to GitHub in 2017 So the answer to “How did Python transform itself into one of the most popular languages?” is still in demand. A few things  had happened that shifted the attitude towards Python and made it more viable as a web development language: FastCGI came, and then WSGI (before that, you had to run Python scripts as ordinary Common Gateway Interface, which wasn’t fast enough). So instead of creating a new process for each request, FastCGI uses permanent processes to handle a series of requests. It increases the speed of implementation and reduces time on development. Prominent universities began using Python in their curriculum, teaching algorithm and other classes (e.g. University of Oxford, Harvard, Binghamton University, Carnegie Mellon University, New York University Polytechnic School of Engineering etc.). Visible developers and standards developers, such as Joe Gregorio and Mark Pilgrim were both using Python to implement the prototypes of the Atom protocol. During that time, Python was stable and has implemented features such as Unicode support, a new Garbage Collector, generators and functional methods, etc. A huge step was applying the Django framework - it’s fast, secure and makes the code clean and easy to write. And Google, of course. It was the main reason why Python had risen so tremendously in literally several years. Google adopted Python back in 2006. They’ve used it as a top-tier implementation language for many platforms and applications since. By reinvesting in development of the language they perfected it and built up the trust. Source: https://stackoverflow.blog/ Java. ‘Java code may never dominate all computers or all platforms, but it is as close to a lingua franca as there is.’ Peter Wayner, InfoWorld. Java is the one that always has been there. It was developed at Sun Microsystems in 1991, and released in 1995. The first ten years were packed with intensive adoption and explosive growth. The developers managed to create something simpler than C++ which equals its performance capabilities. Over time, Sun has released three major versions of Java: 1.0, 1.1 and 1.2. Version 1.2 seems to finally bring Java into the prime time, in particular where user interface tools are concerned. A couple of years later J2SE 1.3 added something new, including the Hotspot JVM, a new version of the Java Virtual Machine (JVM), the sound API and improved debugging. Java core was simple and powerful compared to what they had back there. The role of JVM was crucial. It broke the limitations of that time and significantly drew attention to the Sun’s flagship. Then there were libraries. A huge impact was made, just because from now on developers shifted their focus from struggles with the infrastructure to the application itself. This aspect made Java even more popular than it used to be. Source: StackOverflow Survey 2018 Source: StackOverflow Survey 2018 In 2002, version 1.4 added new tools in the language. And then in 2004, J2SE 5.0 was released, known internally as 1.5. From this point forward Java would be known as Java 5, Java 6, Java 7, and Java 8 and so on. Unfortunately, several years ago Sun Microsystems had ceased to exist being swallowed by the Oracle on January 27, 2010. In the end, Java’s still expected to be everywhere, whether it is a web, desktop or mobile devices. It’s gradually expanding the influence on the whole of modern programming industry. TIOBE index for August 2018 #2:  Functionality Static & Compiled vs Dynamic & Interpreted Static and Dynamic typing: The main idea here is when the types of variables are checked. Statically typed languages define the type of a variable at compile time. In short, types are checked before run-time. For some languages, this means that the programmer must specify what type each variable is (Java, C, C++). The main advantage here is that all kinds of checking can be done by the compiler, and therefore a lot of trivial bugs are caught at a very early stage. Dynamically typed languages are checking types on the fly, during execution. This means that a programmer writes a little quicker because he does not have to specify types every time. Languages that support this type are Perl, Ruby, and Python. Most scripting languages have this feature as there is no compiler to do static type-checking anyway, but you may find yourself searching for a bug that is due to the interpreter misinterpreting the type of a variable. Dynamic typing Static typing Comparison of Dynamic vs. Static Typing in Programming: Dynamic typing associates a type with the value of a variable at runtime, while static typing enforces type checks at compile-time Supporting dynamic typing is an important reason why programmers can be more productive with Python. They simply don’t have to deal with the overhead of Java’s static typing. In the meantime, BECAUSE it is dynamic, there are many design restrictions that are reported by some Python developers and the need to search for bugs every time the code has an error (in static typing the compiler makes it for you). It also requires more testing time, and the errors show up when the applications are finally run. The visible difference looks like that: Java Python Source: https://www.quora.com Interpreted and compiled languages: Python is an interpreted language. In an interpreted language most of its implementations execute the code directly and freely, without previously compiling a program into machine-language instructions. So, while a compiled language after the implementation has ready-to-go instructions for the device you use, in the interpreted language an interpreter interprets the original code every time the program runs. Javacan be either interpreted or compiled. As a compiled language, it has its implementations executed by compilers (translators that generate machine code from source code). Java, C/C++, Assembler, COBOL and many others are translated by running the source code through a compiler. This results in very efficient code that can be executed any number of times. The overhead for the translation is incurred just once when the source is compiled; thereafter, it need only be loaded and executed. Interpreted languages, in contrast, must be parsed, interpreted, and executed each time the program runs, thereby greatly adding to the cost of running the program. Advantages and disadvantages: Interpreted languages: Pros: Good when it comes to the projects with time restrictions on development Ease of future changes to the program Are generally more suited to ad hoc requests, rather than predefined (fixing, editing happens on-the-go) Easier to use (errors are immediately displayed and corrected by a user until the program is able to be executed) Smaller executable package size comparing with a compiled source code Cons: Higher execution costs - more time required for the implementation The interpreted program must be translated every time it is executed Less efficient than compiled programs Interpreters can be 2 to 10 times slower than compilers (they have to translate the same statements over and over again) Compiled languages: Pros: Optimized for the target hardware Fast execution Optimizing compilers may increase speed and decrease the size of a file. Compilers ensure that static variables can be created so that providing less probability of runtime errors Security (the compiled version of a code is not clear and cannot be read this makes application hard for reverse engineering). Cons: Require a compiler (developers need to spend the time to install additional software before they start working on a project) Editing + deploying the code is sometimes much slower than interpreters Performance Python executes with the help of an interpreter instead of the compiler, which causes it to slow down because compilation and execution help it to work normally. On the other hand, it can be seen that it is fast for many web applications too. Python is one of the slowest popular languages around. If you do the same amount of work as a JavaScript program, python takes upwards of 10x the processing, e.g. upwards of 1000x the processing to do the same amount of work as Java or C#): Source: https://benchmarksgame-team.pages.debian.net/benchmarksgame/ The full benchmark of Python vs Java fastest programs (and some more languages) is available here. The speed isn’t Python strong suit. In contrast, Java is faster - high-level languages are expected to act on a high velocity and be genuinely effective, as represented in the graph below: Source: https://medium.freecodecamp.org/ As you can see, the program written in different languages runs consuming a different amount of time. E.g. Python handled this test for 694 secs, comparing to Java that required only 6 seconds. #3: Application Python. ‘Python was so friendly and versatile to begin with that it became viral.’ By Toni Alatalo on Quora.com The most basic use case for Python is as a scripting and automation language. Python isn’t just a replacement for shell scripts or batch files; it is also used to automate interactions with web browsers or application GUIs (Graphical User Interface). Python is also used for system operations, web development, machine learning, server and administrative tools, deployment, scientific modeling and much more. Source: https://stackoverflow.blog/ But, surprisingly, many developers don’t pick up Python as their primary language. Because it’s so easy to use and learn, they choose it as a second or third language. Java is a cross-platform language that is applied in many fields including: Healthcare Finances Government Science Education Transportation, etc. Moreover, Java is highly portable as it must be executed through a cross-platform compatible Java Virtual Machine (JVM). That is why it’ is easily applied on a wide range of hardware devices like television sets, VCRs, toasters and many other devices. Java was, is and will be successfully applied in many domains including, first of all, enterprise and Android applications, experimental stuff, web development and desktop. It won’t be first forever, but shining in its element. Source: http://codingnomads.co/ #4: Ease of use There are two schools of thought about language complexity. One school believes that in order for a programming language to be fully “expressive,” you need an abundance of sophisticated features. Even if these features make the language much bigger, more complex, and much more difficult to learn. Examples include C++, D, Scala, Vala, Rust, and JavaScript. The other school believes in minimalism, in keeping the language small, simple, easy to learn, and easy to use. Examples include Smalltalk, Scheme, Forth, Go, Pascal, and Oberon. Python. Python allows programmers to code faster with less effort. Above all, due to its simplicity and usability, Python is a great language to learn first. But, here comes a disadvantage: while Python lovers become so accustomed to its features and its extensive libraries, they face problem in learning or working on other programming languages. Python experts may see even the requirements of adding curly braces or semicolons as an onerous task. However, because ease of use and fast learning made their contribution, Python drew attention in the late 90s and up to present days. And the output you get is that Python requires less effort compared to other giants, such as C++, Java or even Javascript. Collections described in both languages: Source: https://python-scripts.com/ Java. Java’s simplicity, comparing to its predecessors, also explains the position of Java as one of the most popular programming languages in the world. Add a huge ecosystem packed with libraries and frameworks, a super-optimized JVM runtime, and you have the formula for a killer language. Anyways, nobody refers to Java as the most simple language that is readable for kids. See the example below: “Hello world” written in Java and Python: Source: https://python-scripts.com/ Null in both languages: Source: https://python-scripts.com/ Working with files in Java and Python: Source: https://python-scripts.com/ Java can’t be classified as one of the complex and difficult ones. However, this language is not a piece of cake so you’ve got to make an effort to become totally comfortable with it.   Conclusion The famous guy who created C++ said once: ‘There are only two kinds of programming languages: those people always b*tch about and those nobody uses.’ Bjarne Stroustrup Today, Python is popular because it's easy to get started with, has a lot of libraries and frameworks available, and if you're OK with dynamic types, it's a decent enough language. On the other hand, we have Java. A top-notch language that is applied literally everywhere. A unique set of standard libraries doesn’t concede in any place. The virtual machine that performs greatly on any platform, sturdy garbage collection and the overall ecosystem itself define Java as a beautiful creation that will be in the forefront for a long time. Make your choice that is based on your specific experience and remember, that both Python and Java are worthy to be on top. So, do these programming languages really need to fight? Well, the thing is, they were created for particular purposes and can be successfully implemented in different domains showing unique performance.

What Is Node.js? ‘Node.js extends the creative potential of people with web development experience, enabling a new generation of developers to create servers, command-line tools, desktop apps, and even robots.’ Github.com Node.js enables backend development across multiple platforms with its open-source JavaScript runtime environment.

Key Differences: Node.js vs. Java Performance Node.js Node.js's no-buffering feature outputs data in chunks, resulting in faster runtime. Java Java is a high-performance language, but it might be slower due to its use of compilers. We can see Java's ability to collect garbage as both a benefit and a disadvantage. We’ll observe Node.js and Java efficiency through this benchmark: Java shows itself well: it spends rather less time on handling requests than Node.js. Verdict: Both Scalability Node.js Node.js is a robust platform for building scalable applications that can handle high traffic. The non-blocking input and output system and an event-driven architecture enable it to manage multiple requests simultaneously. Furthermore, Node.js incorporates an event-loop system which permits the server to process a considerable number of requests productively, resulting in increased scalability and efficiency. Node.js takes advantage of a distributed system for greater scalability and efficiency. Java Java is a widely used language for developing enterprise applications, renowned for its superior performance and scalability. To get the best results, developers must use the proper techniques when adding computing resources like RAM and CPUs. Java offers several scaling options, including vertical and horizontal scaling, as well as solutions for the single point of failure issue. Moreover, Java's architecture is highly adaptable, capable of meeting a wide range of application requirements. Through the utilization of external applications, Java may increase its scalability, which it may lack natively. Verdict: Node.js Security Node.js Node.js is vulnerable to security risks, such as the absence of default error handling, which can be a significant safety issue. Moreover, the JavaScript environment used in Node.js is susceptible to attacks like npm phishing and denial-of-service attacks on servers. The JavaScript environment, including Node.js, is prone to Denial of Service (DoS) cyberattacks as a result of protection flaws in third-party npm packages. Java Java is famous for its robust security features, and most of its weak points originate from integration issues rather than inherent flaws in the language design. To further improve safety, developers can use TypeScript, a popular statically typed implementation for languages like Java. This helps prevent type-related errors, while bytecode verification in Java checks all code before running, ensuring an additional layer of protection. Verdict: Java I/O Communication Model IO is decrypted as an Input/Output communication model. Basically, it describes entering or displaying the data and refers to the data itself entered or shown by the computer. There are two types of I/O calls: blocking and non-blocking. Blocking IO means that a thread cannot do anything more until the IO is fully received. While a thread assists an IO request, the non-blocking IO allows it to handle the others, with no waiting for implementation of each (if needed, the request is queued straight away and processed later). Basically, it looks like that: In synchronous I/O, a thread assists a request and enters a wait state until it completes this request. A synchronous type allows a thread to continue processing another request until the operation is complete and decreases the time of implementation. Node.js Node apps are asynchronous and non-blocking. Making synchronous and blocked frameworks, such as ASP.NET and Django asynchronous, will take extra energy. Compared to the others, no additional action needs to be taken with Node.js. Java Java communication is of a blocking nature. The developer here will expect every IO request or start a thread per request. While non-blocking he can send off multiple requests. In current Java versions, both synchronous and asynchronous processes are available (depending on the method, class, and object being called). Verdict: Node.js Single vs Multi-threaded Node.js Node.js is single-threaded, which means that we have one thread to deal with all requests. Once a request arrives, that thread is used to handle it. No need to wait on a database query to return the data. While a database is executing our query, that single thread will serve another request. When the database finishes its job, it puts a message in the Event Queue. Node is continuously monitoring this queue, and after it finds the event, just takes it out and processes it. This kind of architecture makes Node ideal for I/O-intensive apps that include a lot of disk or network access, therefore we can serve more clients, without the need of throwing more hardware. And that is why Node applications are highly scalable. However, a downside to this is that while one client is being serviced, the others have to wait. For that reason, Node shouldn’t be used for CPU-intensive applications (video encoding, image manipulation service etc.). Java On the other hand, Java is multithreaded , which means that they may perform simultaneously several tasks within a program. Whereas other languages require operating system-particular procedures in order to enable multithreading, Java has made multithreaded programming integration smooth. Basically, multithreading helps applications to perform better. So, for large-scale projects that involve concurrency, Java is highly recommended whereas Node.js does not handle the thread and Java does. This is the weakest point of the JS environment. Verdict: Java Speed of coding Node.js A widespread opinion is that Node.js coding is more swift than Java. Note that project type and team size can affect coding speed. Java It often considers the Java programming language requiring more time to write code compared to other languages. However, the actual duration may vary based on various factors, such as the complexity of the project and the number of Java developers involved. Verdict: Node.js Cost of development Factors such as complexity, management, and drawbacks can complicate cost estimation. Getting multiple quotes from various businesses is beneficial to an in-depth perspective of the likely cost. This approach can help ensure that all costs are accounted for, enabling you to make informed decisions about your project budget. Node.js The typical annual salary for a Node.js developer in the United States is over $120k. Java The average annual pay for Java developers in the USA has exceeded $117k. Verdict: Varies Database support Node.js Node.js works well with different databases, including NoSQL and relational databases. This makes it a great fit for NoSQL databases, as it supports storage of data in JSON objects, which complements Node.js' JavaScript-based backends. Node.js also has a dedicated library for object data modeling with MongoDB, which enhances code readability and flexibility, leading to improved developer productivity. Java Popular databases used with Java include MySQL, SQLite, and PostgreSQL. For simpler projects, Java has built-in databases that developers and programmers can use. Additionally, JDBC-enabled databases can address the challenges of relational databases. Verdict: Both Community Node.js Node.js and Java have large and active communities of developers. As Node.js is a more recent technology, its user base is comparatively smaller. Node.js The ability for Node to increase the range of JavaScript and development became clear and led to a rise in popularity. According to StackOverflow, the global usage of this environment breaks the records: The rate ascended from 8% to 26% in four years, and is still going up. The number of countries that accept programming as a key factor for advancement is still on the rise. And the USA, are currently one of the most progressive “employers” in the world: Companies that use Node.js, by the revenue: Node.js only started reaping the benefits of the overall excitement. And there’s a reason: JavaScript became more versatile, Node itself is rather simple in use, novice-friendly and has an extensive “support” for developers (libraries, community etc.). Java Java has been around longer than Node.js, and as a result, it has a larger community of developers. Java has been here over 20 years and is still in demand: Programming may be compared to what is happening in the fashion industry: certain languages may decline in popularity, while others have experienced a surge. People want their new tools to be more simple and omnipresent. And that is the answer why so many people got hooked on Java in the late 90s. The narrative has not changed a great deal; Java is still a language that can be employed on various platforms and for diverse ends. See what countries Java has successfully inhabited: Even-so, the market is ever-evolving. Such giants as C and C++ are not utilized the way they used to be 20 years back. The stability, security, and reliability of Java is why modern IT companies give it a thumbs up. The following TIOBE index graph displayed the total attitude: Verdict: Both Microservices compatibility Node.js The Node.js platform has strong compatibility with code and service modules. Java Java frameworks, such as Spring Boot and Annotation Syntax, offer exceptional compatibility, making it well-suited for the microservice architecture. Verdict: Both Documentation Node.js The Node.js documentation page provides a comprehensive guide to the language, including detailed API reference documentation, information on ES6 features, and helpful guides to assist developers in using Node.js effectively. Java Java's documentation is a comprehensive and invaluable asset for developers regardless of their experience. This language is abundant in information, from commonplace to more specialized features. This gives developers a thorough comprehension of the language and its potential. Verdict: Both Easiness to learn Node.js Its syntax and JavaScript interpretation make Node.js easier to learn, especially for those familiar with JavaScript. It provides a better coding experience and simplified coding syntax, making it an appealing choice for constructing efficient and scalable applications.
