What is method overriding in Object Oriented Programming?

Method overriding is a concept in Object Oriented Programming (OOP) where a subclass provides a different implementation of a method that is already defined in its superclass. In other words, it allows a subclass to provide its own implementation of a method inherited from its superclass.

When a method is overridden, the subclass provides a specific implementation of the method that is more appropriate for its own context. This allows the subclass to modify the behavior of the inherited method without changing its signature.

To override a method, the subclass must have the same method name, return type, and parameter list as the method in the superclass. The access modifier of the overridden method in the subclass should be the same or more accessible than the access modifier of the method in the superclass.

When an object of the subclass is created and a method is called, the JVM determines which version of the method to execute based on the actual type of the object at runtime. If the method is overridden in the subclass, the JVM executes the overridden version of the method instead of the superclass version.

Method overriding is a powerful feature of OOP as it allows for polymorphism, which means that a single method can have different implementations in different classes. This enables code reusability, flexibility, and extensibility in software development.

In summary, method overriding in Object Oriented Programming is the ability of a subclass to provide its own implementation of a method inherited from its superclass, allowing for customization and modification of behavior.
