Write a JAVA program that illustrates simple inheritance.

Aim: Write a JAVA program that illustrates simple inheritance.

Program:

class Calculation 

{

   int z;

   public void addition(int x, int y) 

   {

      z = x + y;

      System.out.println("The sum of the given numbers:"+z);

   }

   public void Subtraction(int x, int y) 

   {

      z = x - y;

      System.out.println("The difference between the given numbers:"+z);

   }

}

public class My_Calculation extends Calculation 

{

   public void multiplication(int x, int y) 

   {

      z = x * y;

      System.out.println("The product of the given numbers:"+z);

   }

   public static void main(String args[]) 

   {

      int a = 20, b = 10;

      My_Calculation demo = new My_Calculation();

      demo.addition(a, b);

      demo.Subtraction(a, b);

      demo.multiplication(a, b);

   }

}

Output:
