Fastest way to convert Scala array to Java array

Question

I have a method in Java with this signature void setActiveProfiles(String... profiles), and in Java I can pass an array of string to this method. I want to call the method and pass it an Array[String], but I got Type mismatch error. And my question is what is the best and optimal way to convert Scala array to Java array?

This is the body of compilation error:

type mismatch;
 found   : Array[String]
 required: String

Can you display the error. Are you trying to send Java array to scala function? — Jatin

No, I want to call the Java method with vararg parameter in Scala — Pooya

You dont have to do anything. If you have a java function and it expects a String[] then scala compiler will itself convert Array[String] to String[]. Please show the error — Jatin

I've found the answer and I've tested it, call method as setActiveProfiles(array:_*)
