This tutorial walks you through creating an easy Hello World application using IntelliJ IDEA.
In this tutorial, we have to use IntelliJ IDEA. To get started, install the most recent version of IntelliJ IDEA.
Kotlin is bundled with version 15 with the IntelliJ IDEA.
You can download the free community version (or the full-final version) from the JetBrains website.
As an alternative to using IntelliJ IDEA, you will compile and execute Kotlin applications using the instruction compiler. For details, see Working with the instruction compiler.
If you are new to JVM and Java, observe the JVM Minimal Survival Guide. If you are the new IntelliJ IDEA, then observe the IntelliJ IDEA Minimum Survival Guide.
Once you have the IntelliJ IDEA installed, it is time to build your first Kotlin application.
Now you have a new project created with the following folder structure:
Now the application is ready to run. The easiest way is to click on the green run icon in the gutter and choose the run ‘app.kt’.
If all goes well, you will see the result in the tool window.
congratulation! Now you have your first Kotlin application running.
