Can we override the variables in class like we do for a Method? | Core Java Forum

Hi Yogesh,

In case of inheritance we can overrite the one method in another class but can we do the same for variables as well?

Yes. We can inherit any functionality from parent class in child classes, be it method, variables, using constructors with super keyword or even inner classes also


See this example for variables and methods:


class Calculation {
   int z;
   public void addition(int x, int y) {
      z = x + y;
      System.out.println("The sum of the two numbers is:"+z);
   public void Subtraction(int x, int y) {
      z = x - y;
      System.out.println("The difference of two numbers is :"+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);
