Hands-On Object-Oriented Programming with Kotlin

Function overloading

Function-overloading is a feature where a class has more than one function with the same names. Each function is uniquely identified by its parameters. In the following example, a Person class contains two functions with the same name – fun greet(), which doesn't contain any parameters, and fun greet(message : String), which contains one string parameter. Kotlin can determine the function call by the parameters provided:

class Person (val name: String, var age : Int , var height : Double){    fun speak(){        println("My name is $name , i am $age years old and         I am $height feet tall")    }       fun greet(message : String){        println("Hi I am $name.... $message")    }    fun greet(){        println("Hi I am $name.... Nice to meet you!!!")    }}fun
