Java came into existence 23 years ago. This so-long survival indicates its ability to meet modern challenges in the development world. It holds a supreme position in the list of following C and C++, setting the highest usability record with millions of developers and systems. most popular programming languages Not only tech-world but the non-tech world is also aware of Sun Microsystems’ Java programming language. Java is considered as a go-to programming language for larger enterprises. It dominates the enterprise application development world with its extraordinary features like interoperability and flexibility. However, the rise of mobile shifted the whole paradigm. Java has been amidst the primary languages in Android app development along with Scala and Groovy. And now, Kotlin has turned the table. Do You Know? James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in 1991. Java has proven its ability to become one of the popular and powerful programming languages for the corporate world. It’s not ‘legacy’ language as people are still using it in their development environments. Leading job portals consider ‘Java’ language in the index of most-demanding programming language due to its simplicity, robustness, and influential approach. Java’s architectural OOP paradigm and massiveness of code are the two major reasons why many applications are still being written in Java. Over time, the learning focus has been transferred to the modern and rich languages, but ‘introduction to the programming world’ still involves languages like Java, C, and C++. With emerging mobile technologies, Java is rated as less mobile-oriented and with slower updates. Here, one thing you need to keep in mind that Google’s Android operating system uses Java API packages. The Java vs. Kotlin debate is in the trend but our question is something different. Do you think using Kotlin in android app development bring you success? How Kotlin is making Android development game stronger? Let’s find answers. Kotlin for Android: Scoring High or Roaring High? In 2017, at Google I/O, . Kotlin was announced as an official language for Android development It’s well-known fact that each and every technology has something different to offer. Updates in the older one and introductions to the newer technologies are not new to us. Mobile-ready language is the first and foremost requirement of today’s world. Optimization is second. While Java is almost ruling enterprise world, Kotlin is emerging as among Android developers. Certainly, there should be several reasons behind its popularity over Java. most loved programming language Java vs. Kotlin: Will Kotlin Replace Java? Here’s The Answer Certainly, Kotlin’s widespread usage in no time indicates its ability to replace Java, but Java’s ecosystem is quite large and Kotlin is influenced by Java to a greater extent. As of now, it seems unfeasible considering Java’s grown-up community. Let’s dig a little deeper. Java is an object-oriented, widely-used, standard, and stable language in the programming world. What Is Kotlin? Kotlin is considered as statically typed programming language that runs on JVM(Java Virtual Machine). It is developed by JetBrains and open-source community. The ‘Kotlin’ name came from Kotlin Island located near the Saint Petersburg. It is supported by leading IDEs and compatible for Java 6 or Java 8. Android is written in Java along with C and C++, and this could be a reason why Android developers are more inclined towards the use of Java. Write once, run anywhere principle of Java suggests that compiled code can run on all Java-supportive platforms without the need of recompilation. This principle contributed a lot in making Java more popular and second most active language on GitHub. Here are several pros of Java language: It’s easy to understand and learn Easier to execute — run code in a browser or in a virtual machine Open-source and up-to-date, and feature-rich programming language Ability to assemble large projects precisely with the help of modern tools Wide community support that keeps Java up-to-date Owned by Oracle Corporation who is dedicated to making it stronger Android depends on Java language Flexibility for cross-platform app development Automatic and effective memory management makes it portable to use on a range of devices from large networks to the lowest PCs There are many advantages of Java that clearly represent its recognition among the developers’ community and enterprises. Kotlin’s Answer To Java’s Limitations No doubt, Java ranks as one of the widely-used programming languages, but the cons of Java happened to be the reasons behind the creation of more advanced programming language. Take a look at some drawbacks of Java and how Kotlin can be the solution to those. Image Credit: https://kotlinlang.org/ In Java, you would require to write more code: Java is a verbose language. You need to write more and lengthy code that usually contains more errors and bugs. Consider this example, A simple “Hello World” program in Java: class HelloWorldApp{    public static void main(String[] args) {        	System.out.println("Hello World!");	}} A similar program in Kotlin: package hellofun main() {println("Hello World")} It’s that simple! Kotlin uses developer-friendly coding structures and norms that are easy-to-understand and use. When you consider this example from the developers’ perspective, you will be able to understand why Kotlin is loved by developers around the world. It is concise, effective, and faster compared to Java. Moreover, there will be less chance of errors and bugs, resulting in cost and time reduction. In case of longer code compilation, Kotlin is preferred over Java This seems quite obvious. When you have larger applications or a bunch of files to be executed, Java is somewhat less considered in terms of speed. Speed isn’t truly a significant factor of comparison as Kotlin is fundamentally same as Java and both generate byte-code. The speed of compilation depends on the code you write and there isn’t any measurable difference between both the languages in terms of speed. However, the capability to assemble and separate large applications into layers has been an advantage for the Java developers with the extra benefit of faster compilation. On the other side, Kotlin provides a performance boost in some cases. Focus On Optimizing Android Code: Kotlin is backed by JetBrains, the organization who also owns IntelliJ IDEA, the powerful Java IDE (Integrated Development Environment) and several others. This community is dedicated to making android app development smoother, faster, and more effective than it happens to be with Java. While Java was built years ago when Android wasn’t introduced, somewhere, it lacks a mobile-first approach in the development. Java vs Kotlin: Several Things From Developers’ Perspective Kotlin offers many advanced programming features than Java. Take a look at the comparison of features (developers’ perspective): Additional Advantages Of Kotlin: Kotlin is interoperable Kotlin is interoperable with Java, meaning that you can leverage all existing Java libraries, JVM, and frameworks. Easy learning curve The developers who know Java can easily learn Kotlin. Switching from Java to Kotlin does not have much overhead and adopting it doesn’t cost anything. Similar To Apple’s Swift Yes, Kotlin is much like Apple’s Swift language in terms of language features and flexibility. Who Is Using Kotlin in Their Development Environments? Pinterest Evernote Uber Corda Gradle Pivotal Coursera Atlassian We have discussed the advantages and features of Kotlin. Now, we are moving forward with its drawbacks: Cons Of Kotlin Programming Language: Limited learning resources as it is a small and new community It may become a challenge to switch from Java to Kotlin for your team Finding Kotlin developers seems difficult than Java developers Sometimes compilation is slower compared to Java What Should You Choose To Develop Your Next App? Certainly, Kotlin can give a competitive edge. It saves your time and efforts in development achieving faster time-to-market of your app. Choose Kotlin When You have Kotlin developers who have experience in developing apps in Kotlin When you want to give a modern, fresh look to your application When you want to accomplish faster time-to-market of app When your team has proper knowledge of frameworks and tools Remember, Java is still here and a complete shift to Kotlin seems impossible as there is tons of code already written in Java. Final Thoughts: A comparison is always subjective. There are many factors and perceptions that matter a lot when we compare any languages, frameworks, or tools. We know that Kotlin is based on Java and you can’t actually compare both these languages due to an influence of one on the other. Many have adopted Kotlin and are enjoying tangible benefits of it, and there are developers who are stuck with Java in android app development. One thing is certain that Kotlin has potential to replace Java language but it may take more time than we imagine. This post was originally published on our Blog here
