How to use Array[String] in a function expecting String* in Scala

Question

I have a function in Scala that requires a String vararg, i.e. String*. How can I call that function if I have an Array[String]?

A word of notation: String * isn't a type, so "convert to String *" doesn't really make sense. The question here is how to call a varargs function with an Array. — Chris Martin

You can use : _* for that

def f(strings: String*) {
  ...
}

f(Array("a", "b", "c"): _*)

no `: _*' annotation allowed here (such annotations are only allowed in arguments to *-parameters)

Sorry, I made a mistake.
