A java program using super keyword !!!

• Constructors use super to invoke the superclass’s constructor. If a constructor uses super, it must use it in the first line; otherwise, the compiler will complain.

If your method overrides one of its superclass’s methods, you can invoke the overridden method through the use of the keyword super. You can also use super to refer to a hidden field (although hiding fields is discouraged). Consider this class, Superclass:

public class Superclass {

public void printMethod() {
System.out.println(“Printed in Superclass.”);

Here is a subclass, called Subclass, that overrides printMethod():

public class Subclass extends Superclass {

// overrides printMethod in Superclass
public void printMethod() {
System.out.println(“Printed in Subclass”);
public static void main(String[] args) {
Subclass s = new Subclass();
