EXERCISE 112 : Override methods in JAVA

Objectives

At the end of this exercise you shall be able to
• develop Java programs to Override methods in JAVA.

Requirements

Tools/Materials
• PC / laptop with windows OS
• SDK software
• Test editor (Visual studio/ subline/ notepad)

Procedure

In Java, method overriding is a mechanism by which a subclass provides a specific implementation of a method
that is already provided by its superclass. The overridden method in the subclass should have the same signature
(name, return type, and parameters) as the method in the superclass.

TASK 1: Here’s a basic example of method overriding in Java:
// Base class (Superclass)
class Animal {
// Method to make a sound
public void makeSound() {
System.out.println(“Some generic animal sound”);

}
}
// Derived class (Subclass) extending Animal
class Cat extends Animal {

// Override the makeSound method from the Animal class
@Override
public void makeSound() {
System.out.println(“Meow!”);
}

// Additional method specific to Cat
public void purr() {
System.out.println(“Purring...”);
}

}
// Main class to demonstrate method overriding
public class MethodOverrideExample {
public static void main(String[] args) {
