Program for method overloading in Kotlin

package com.includehelp

//Declare class
class Operation{
    //Member function with two Int type Argument
    fun sum(a:Int, b:Int){
        println("Sum($a,$b) = ${a+b}")
    }

    //Overloaded Member function 
    //with three Int type Argument
    fun sum(a:Int, b:Int,c:Int){
        println("Sum($a,$b,$c) = ${a+b+c}")
    }

    //Overloaded Member function with 
    //four Int type Argument
    fun sum(a:Int, b:Int,c:Int,d:Int){
        println("Sum($a,$b,$c,$d) = ${a+b+c+d}")
    }
}

//Main function, entry Point of Program
fun main(args:Array<String>){
    //Create Instance of Operation class
    val operation = Operation()

    //Called function with two arguments
    operation.sum(10,20)

    //Called function with three arguments
    operation.sum(a=2,b=3,c=5)

    //Called function with four arguments
    operation.sum(5,8,2,12)
}

Output:

Sum(10,20) = 30
Sum(2,3,5) = 10
Sum(5,8,2,12) = 27
