The Rise of Kotlin Programming Language

On 17 May 2017 the Android Team announced first class support for Kotlin and made it the official programming language for the Android applications. This badge had previously been given to programming languages like C++ and Java. But how did it all happen and why? Does the emergence of Kotlin mean the down for Java? In this article we will be finding the answers to these questions.

The Rise of Kotlin

For years Java used to serve the Android Community. Millions of applications are developed and it was the undefeated ruler of the Android world. But due to some of its drawbacks like lengthy code, null pointer exception and less control over garbage collection, gave chance to other new programming languages to take its place. Although Scala programming language had great features comparing to Java, it could not satisfy the needs of the programmers. Until Kotlin came in to existence.

Kotline was developed by JetBrains and it is named after an Island. It was made official in 2016 and its stable release which is Kotlin version 1.1.3 came in June 2017. Kotlin can be used to develop applications for Java Virtual Machines, Android, Browsers and Native.

Why Kotlin?

Kotline, this newly emerged programming language is gradually gaining fame with its great potential towards the Android Application Development. Here we list some reasons that you should probably start using Kotline;

  • Lesser code

Compared to Java syntax, Kotline syntax is shorter and hence it is faster to execute. Moreover; Java is too old and with every update it becomes harder for it to support both the old and the new features.

  • Automatic Java to Kotline converter

Android Studio version 3 has an inbuilt feature which automatically converts the files written in Java into Kotline. This feature is even usable to very long and complex applications, too.

  • Interoperability with Java

Kotline’s syntax is not actually compatible with Java but it is indeed interoperable. Programmers can now develop codes in Kotline that will execute alongside the existing Java code. In addition, Kotline doesn’t enforce any specific programming philosophy like Object Oriented or Functional.

  • Completely free

Kotlin doesn’t cost anything. It is open source and Kotlin programs can make use of all the existing Java libraries and frameworks. Additionally, Kotlin is very easy language to learn.

  • Null Safety

While you develop android applications you must use null quite a lot of time in order to show the absence of a value. Well, Kotlin has the null in its type system.

The Future

Well, every programming language has its own pros and cons. Kotlin also does. But up to date it is the best choice of application development you could have with its easy to learn and short syntax and fast execution features. Kotlin has furthermore great commercial support and it is growing very fast. It seems like very soon it is going to rule the Android Community.
