How to make vararg parameter which gets at least one argument?

Question

I have the following code:

fun qwer(vararg x: String){
}

fun main() {
    qwer()
}

As you can see i can pass 0 strings to qwer function. Is there a way to make qwer function get at least one argument ?

Answer 1

You could do something like this:

fun qwer(first: String, vararg x: String) {

}

So, calling qwer() errors out but qwer("hello") is fine.
