I have this code. How to make it jump out of while loop? I mean what should be input? I have entered nothing and just pressed the enter button but it takes it as string. And I also tried 0 and it did not work. "this line" never being printed to console. any ideas?

fun main(args: Array<String>) {
    var line = readLine()
    while (line !=null) {
        println(line)
        line = readLine()
    }
    println("this line")
}
