6. What is the output of the following code class A { public int i; void display () { System.out.println (i) class B extends A { public int j; void display () { System.out.println (i)

Q-2) Given the following code: 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 c) Give the output when this program is run: 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); Complete the missing lines in a and b a) Name the superclass the subclass b) Suppose we wish to save the program in a text file My_Calculation. The extension should be d) Which objects (variables and methods) are inherited from the superclass? e) If you instantiate demo as Calculation demo = new My_Calculation(); in the main…
