Default arguments in Functions
You can specify a default value for a function parameter. The default value is used when the corresponding value is omitted from the function call. fun main(args:Array<String>) { println ( findVolume ( 5 , 5 )) //5*5*20 //Here the 3rd parameter it will take default parameter value println ( findVolume ( 5 , 5 , 5 )) //5*5*5 //Here the 3rd parameter replaced the default value } fun findVolume(length:Int,width:Int,height:Int= 20 ):Int { return length*width*height } Output: 500 125 Can we call default functions from Java file? Yes, Java doesn't have any default parameter functions for this we have to use jvm annotations @JVMOverloads this will give the interoperability between java class file and kotlin file. Volume.Kt fun main(args:Array<String>) { println ( findVolume ( 5 , 5 )) //5*5*20 println ( findVolume ( 5 , 5 , 5 )) //5*5*5 } fun f...
