How to define scala function with undefined number and type of arguments

Question

My function must take a list of values as argument, convert each one to string and add them to a list. The values can be either String, Int or Boolean.

How to define a function with the flexibility to handle the different types? Here is my initial function but as expected when i give int as argument, i get an type mismatch error

def test (s: String*): List[String] = {
  s.toList
}

Thanks. Exactly what i wanted. i've been able to trim and uppercase each string as needed. – djohon Jul 25 '18 at 11:23

@C4stor No, I can't. ;) (Not sure whether the first commenter is notified in such cases) – Andrey Tyukin Jul 25 '18 at 14:54
