How to pass Scala array into Scala vararg method?

Question

Consider the code below:

private def test(some:String*){

}

private def call () {
  val some = Array("asd", "zxc")
  test(some)
}

It prints expect String, found Array[String] Why? Are Scala varargs not arrays?

Note

I found several questions on Stack Overflow about Scala varargs, but all of them are about calling Java varargs methods or about converting Scala lists to arrays.

Answer 1

Append :_* to the parameter in test like this

test(some:_*)

And it should work as you expect.

If you wonder what that magical :_* does, please refer to this question.

Answer 2

It is simple:

def test(some:String*){}

def call () {
  val some = Array("asd", "zxc")
  test(some: _*)
}
