// Base parent (Super class) open class Person { } // Childe class (Sub class) class Students: Person() { }Here is an example with constructor:
open class Person(val name:String,val age:Int){ } //Inheritance for Employee from Person class class Employee(name:String,age:Int, val salary:Int):Person(name,age){ }Here is the complete code with intanciation :
open class Person(val name:String,val age:Int){ } //Inheritance for Employee from Person class class Employee(name:String,age:Int, val salary:Int):Person(name,age){ } fun main(args: Array< String >) { //Create object Person P var E=Employee("Richard",35,28000) println("Empoyee name is : " + E.name) println("The Employee's age is : " + E.age) println("The Employee's salary is : " + E.salary) }Inheritance from the methods of the super class.
Here's an example of a child class: Rectangle that inherits the perimeter method from the super class Parallelogram:
open class Parallelogram(val side1:Int,val side2:Int){ fun perimeter():Int{ return 2*(this.side1+this.side2) } } //Inheritance for Employee from Person class class Rectangle(side1:Int,side2:Int):Parallelogram(side1,side2){ } fun main(args: Array< String >) { //Create object Rectangle var R=Rectangle(10,7) println("The perimeter of rectangle R is : " + R.perimeter()) }
