Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes .

Method Overriding Example We have two classes: A child class Boy and a parent class Human. The Boy class extends Human class. Both the classes have a common method void eat() . Boy class is giving its own implementation to the eat() method or in other words it is overriding the eat() method .

The @override annotation applies to instance methods, instance getters, instance setters and instance variables (fields). When applied to an instance variable, it means that the variable’s implicit getter and setter (if any) are marked as overriding. It has no effect on the variable itself.
