Rough estimation indicates that using Kotlin allows you to cut off the lines of code by approximately 40% (compared to Java).Įxpressive means, it's easy to write code that both humans and compilers can understand easily. For more information, visit Mixing Java and Kotlin in One Project. This means all your current Java/Android code works seamlessly with Kotlin. It is 100% interoperable with Java and Android. The Kompiler (Kotlin compiler), IntelliJ IDEA plugin, enhancements to basic Java libraries and build tools all are open source. Kotlin is distributed under Apache License, Version 2.0. To get started with Kotlin programming, visit our Kotlin Tutorials.įeatures of Kotlin Programming Open Source It is because Kotlin is safe, concise, and fun to read and write. Nowadays, Kotlin is widely used for Android development instead of Java. $ kotlinc -script list_folders.Kotlin is a relatively new programming language developed by JetBrains for modern multiplatform applications. To run a script, we just pass the -script option to the compiler with the corresponding script file. Using our favorite editor, we create a new file called hello.kt with the following: fun main(args: Array) $ brew updateĬreate a simple application in Kotlin that displays Hello, World!.
Next open a new terminal and install Kotlin with: $ sdk install kotlinĪlternatively, on OS X you can install the compiler via Homebrew.
Simply run the following in a terminal and follow any instructions: $ curl -s | bash SDKMAN!Īn easier way to install Kotlin on UNIX based systems such as OS X, Linux, Cygwin, FreeBSD and Solaris is by using SDKMAN!. The bin directory contains the scripts needed to compile and run Kotlin on Windows, OS X and Linux. Unzip the standalone compiler into a directory and optionally add the bin directory to the system path. This tutorial walks us through creating a Hello World application using the command line compiler.Įvery release ships with a standalone version of the compiler.
