Using super to call the superclass of Dog (subclass):

class Animal { // Superclass (parent)

  public void animalSound() {

    System.out.println("The animal makes a sound");




class Dog extends Animal { // Subclass (child)

  public void animalSound() {

    super.animalSound(); // Call the superclass method

    System.out.println("The dog says: bow wow");




public class Main {

  public static void main(String args[]) {

    Animal myDog = new Dog(); // Create a Dog object

    myDog.animalSound(); // Call the method on the Dog object




Definition and Usage

The super keyword refers to superclass (parent) objects.

It is used to call superclass methods, and to access the superclass constructor.

The most common use of the super keyword is to eliminate the confusion between superclasses and subclasses that have methods with the same name.

To understand the super keyword, you should have a basic understanding of Inheritance and Polymorphism.
