Kotlin - Its Not Just Hello World

fun main(args : Arrays<String>){

println("Its not just a Hello world..!!!");

     // Yes ... No need to write boiler plate code now..!!!

 without class we can write code in kotlin , yes internally

 compiler creates class for us.

 compiler generated class name - filename with Kt append - filenamKt

 kotlinc filename.kt - complie

 kotlin finlenameKt  - Run

output -

 
Its not just a Hello world..!!!

=======================================================

2. If You want to create main method which is static in nature inside

class then try following snippets

class Demo {
    companion object {
        @JvmStatic fun main(args: Array<String>) {
            println("Hello Kotlin");
        }
    }
}

Note - class in kotlin is default public and final

==================================================================

3.If you want to create main method or any static method -

 there are two ways

1. create companion onject block as above or

2. make object class -

object Demo {
 @JvmStatic fun main(args: Array<String>) {
            println("Hello Kotlin")
    }
}
