In this example, you’ll how in Java to show concept of multilevel inheritance.

import static java.lang.Math.*; class A { private int num1,num2,sum; public void set(int x,int y) { num1=x; num2=y; sum=num1+num2; } public int get1() { return(sum); } } class B extends A { public void display() { System.out.println("sum of two numbers is"+get1()); } } class C extends B { private double sqr; public void sqrs() { System.out.println("square root of sum is"+sqrt(get1())); } } class ABCMain { public static void main(String args[]) { C obj1=new C(); obj1.set(100,200); System.out.println("first number is 100"); System.out.println("second number is 200"); obj1.display(); obj1.sqrs(); } }
Code language: Java (java)

OUTPUT

This program does a pretty good job. Here is a sample execution

first number is 100
second number is 200
