Method Overriding - The Foundation of OOP: Method overriding is a crucial concept in Object-Oriented Programming (OOP) and is essential in Java. It allows a subclass to provide a specific implementation of a method that is already defined in its superclass. Here's a breakdown of the key aspects of method overriding:

1. Inheritance:

   • Method overriding is directly related to inheritance, one of the core principles of OOP. It enables a subclass to inherit the methods and properties of its superclass.

2. Superclass and Subclass:

   • In method overriding, you have a superclass (parent class) and a subclass (child class).

3. Overriding Rules:

   • To perform method overriding successfully, you must follow specific rules: a. The method in the subclass must have the same name, return type, and parameter list as the method in the superclass. b. The method in the subclass must be marked with the @Override annotation to indicate that it's intended to override a method in the superclass.

4. Access Control:

   • The overridden method in the subclass should not have a more restrictive access modifier than the method in the superclass.

5. Polymorphism:

   • Method overriding is a manifestation of polymorphism in Java, allowing objects of different classes to be treated as objects of their common superclass.

Benefits of Method Overriding:

• Achieves runtime polymorphism, allowing dynamic method invocation based on the actual object type.
• Enhances code reusability by promoting the use of a common interface in different subclasses.
• Facilitates the "IS-A" relationship between the subclass and the superclass, promoting a clear hierarchy.

Method overriding is a fundamental concept in object-oriented programming (OOP) that allows a subclass to provide a specific implementation of a method that is already defined in its superclass. In other words, when a subclass provides a specific implementation for a method that is already defined in its parent class, it is said to be overriding that method.
