Creating a Multilevel Inheritance Hierarchy in Java

Inheritance involves an object acquiring the properties and behaviour of another object. So basically, using inheritance can extend the functionality of the class by creating a new class that builds on the previous class by inheriting it.

Multilevel inheritance is when a class inherits a class which inherits another class. An example of this is class C inherits class B and class B in turn inherits class A.

A program that demonstrates a multilevel inheritance hierarchy in Java is given as follows:

Example

 Live Demo

class A {    void funcA() {       System.out.println("This is class A");    } } class B extends A {    void funcB() {       System.out.println("This is class B");    } } class C extends B {    void funcC() {       System.out.println("This is class C");    } } public class Demo {    public static void main(String args[]) {       C obj = new C();       obj.funcA();       obj.funcB();       obj.funcC();    } }

Output

This is class A This is class B This is class C
