Question

Add another subclass division to the example below:

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);

}

}

Answer 1

Calculation.java :

//Java class
public class Calculation {
   int z;

   // method for addition of two numbers
   public void addition(int x, int y) {
       z = x + y;
       System.out.println("The sum of the given numbers:" + z);
   }
   //method for subtraction of two numbers
   public void Subtraction(int x, int y) {
       z = x - y;
       System.out.println("The difference between the given numbers:" + z);

   }
}

******************************

division.java :

//Java class
public class division extends Calculation {
   //method to divide a number by another number
   public void divide(int x, int y){
       z = x/y;
       System.out.println("The division of the given numbers:"+z);

       }
}
***********************************

My_Calculation.java :

//Java class
public class My_Calculation extends Calculation {
   // method to calculate multiplication
   public void multiplication(int x, int y) {
       z = x * y;
       System.out.println("The product of the given numbers:" + z);
   }

   // main method entry point of the program
   public static void main(String args[]) {
       int a = 20, b = 10;// declaring variable
       // creating object of My_Calculation
       My_Calculation demo = new My_Calculation();
       demo.addition(a, b);
       demo.Subtraction(a, b);
       demo.multiplication(a, b);
       //creating object of division
       division d=new division();
       d.divide(a, b);//calling method with division object
   }
}
