method signatures in scala : Map(String, Int)

I want to declare a method explicitly with a return type as in : 

def method() : Int = {}

But I want to return a Map((String,Int)) instead. So far I couldnT make it work.

Is this an invalid method signature in scala? if so why?

def parseEmptySpaceLine0 (array: Array[String]): Map(String, Int) = { 

 //stuff
 Map("", 1)
 }

Generic type parameter should be enclosed in [], not in (). Much like the Array[String] in your signature.

So it's Map[String, Int] you're looking for.
