Setting Up the Kotlin Environment in IntelliJ IDEA

The free Community Edition of IntelliJ IDEA can be downloaded from: https://www.jetbrains.com/idea/download/index.html

After downloading and installing, we can use this tool to create projects. During the creation process, you need to select the SDK, and Kotlin can be used together with JDK 1.6+.

Check the Kotlin (Java) checkbox in the dropdown menu on the right.

Next, let's choose a project name: HelloWorld

After the project is created, the file structure is similar to that of Java.

Next, we click on the src folder and create a Kotlin file, which can be named arbitrarily. Here, we create app.kt.

Now, let's write some code in the app.kt file. IntelliJ IDEA provides us with a template to quickly complete this operation. Just type main and press Tab.

Now let's add a line of code to print "Hello, World!".

Next, we can click on the Kotlin icon in the upper left corner of the editor and select Run 'AppKt' to run the code:

After the code runs successfully, you can see the result in the Run window.

In this way, our first Kotlin code is running.
