What is Kotlin?

Kotlin is a modern, statically typed programming language that runs on the Java Virtual Machine (JVM) and can also compile to JavaScript or native code. Created by JetBrains in 2011 and officially released in 2016, Kotlin has become the preferred language for Android development (Google announced official support in 2017).

It’s designed to be:

Concise — less boilerplate than Java
Safe — built-in null safety to avoid NullPointerExceptions
Interoperable — works seamlessly with existing Java code
Versatile — can be used for Android, backend, desktop, and multiplatform apps

Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.).

It is used for:

Mobile applications (Android apps)
Desktop applications
Web applications

Games
Database connection

Is one of the most popular programming languages in the world. It has a large demand in the current job market. It is open-source and free. It is secure, fast and powerful. It has huge community support (tens of millions of developers). As Java is close to C++ and C#, it makes it easy for programmers to switch to Java or vice versa.

1991 (June):

Java language project initiated by James Gosling: James Gosling begins the Java language project for use in set-top box projects. The language is initially called ‘Oak’ (after an oak tree outside Gosling’s office) and also goes by the name ‘Green’. The initial choice for development was C++, but due to high memory usage, a new language (GreenTalk) was started. The file extension used for GreenTalk was .gt.
