How to run single Kotlin class from Android Studio

Question

I am new to Kotlin development and I have created a separate Kotlin class in Android Studio as below :

  class MainClass{

    fun main(args: Array<String>)  {
        println("Hello World");
    }
 }

But, How can I run this kotlin class, and where the output will be generated.

Answer 1

your main function has to be a top-level function. Try this:

fun main(args: Array<String>)  {
        println("Hello World");
    }

In order to run it, just click on green the icon next to the function name in AS.
