Kotlin program for Default and named argument of a function

package com.includehelp

// function with Default and named Arguments
fun printCountryDetails(countryName: String="India",noOfStates: Int=30){
    println("Country : $countryName")
    println("No. of States in $countryName : $noOfStates")
}

// Main function, Entry Point of Program
fun main(args:Array<String>){
    // Call function without parameter so 
    // default value passed to function
    printCountryDetails()

    // Call function with parameter value
    printCountryDetails("America",51)

    // call function with only one parameter, 
    // so for second argument default value 
    // of argument will be used
    printCountryDetails("Australia")

    // call function with named argument, 
    // we write function argument name while 
    // calling function
    printCountryDetails(countryName = "Japan",noOfStates = 15)
}

Country : India
No. of States in India : 30
Country : America
No. of States in America : 51
