Scala Functions - Default Parameter Values
\n\n
![Image 3: Scala Functions]()
Scala Functions\n\nScala allows you to specify default parameter values for function parameters. When using default parameters, you do not need to provide arguments for them when calling the function; the function will use its default parameter values. If you do provide arguments, the passed values will override the default values. An example is as follows:\n\n
object Test { def main(args: Array) { println( "Return Value : " + addInt() ); } def addInt( a:Int=5, b:Int=7 ) : Int = { var sum:Int = 0 sum = a + b return sum }}
\n\nExecuting the above code, the output result is:\n\n
$ scalac Test.scala $ scala TestReturn Value : 12
