Scala Specifying Function Argument Names

Scala Functions

Generally, when calling a function, the arguments are passed in the order in which the parameters are defined in the function. However, we can also pass arguments to a function by specifying the argument names, without having to follow the order. Here is an example:

object Test {
   def main(args: Array[String]) {
        printInt(b=5, a=7);
   }
   def printInt( a:Int, b:Int ) = {
      println("Value of a : " + a );
      println("Value of b : " + b );
   }
}

After executing the above code, the output will be:

$ scalac Test.scala
$ scala Test
Value of a : 7
Value of b : 5
