Scala Named Function Parameters

Scala Functions

In general, when calling a function, the parameters are passed one by one in the order of the function definition. However, we can also pass parameters to the function by specifying parameter names without following the order, as shown in the following 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 is as follows:

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