What is overriding in OOP with example?

Overriding is an object-oriented programming feature that enables a child class to provide different implementation for a method that is already defined and/or implemented in its parent class or one of its parent classes. Overriding enables handling different data types through a uniform interface.

Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters. One of the methods is in the parent class, and the other is in the child class.

The ability of a subclass to override a method allows a class to inherit from a superclass whose behavior is “close enough” and then to modify behavior as needed. The overriding method has the same name, number and type of parameters, and return type as the method that it overrides.

Function overriding in C++ is a feature that allows us to use a function in the child class that is already present in its parent class. Function overriding means creating a newer version of the parent class function in the child class.

When two or more methods in the same class have the same name but different parameters, it’s called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it’s called Overriding.

What is Overloading and Overriding? When two or more methods in the same class have the same name but different parameters, it’s called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it’s called Overriding.

Method overloading is performed within class. Method overriding occurs in two classes that have IS-A (inheritance) relationship. In case of method overloading, parameter must be different. In case of method overriding, parameter must be same.

Method overriding is one of the way by which java achieve Run Time Polymorphism. The version of a method that is executed will be determined by the object that is used to invoke it.

The compiler does not consider the return type while differentiating the overloaded method. But you cannot declare two methods with the same signature and different return type. It will throw a compile-time error.

Method overloading is used to increase the readability of the program. Method overriding is used to provide the specific implementation of the method that is already provided by its super class. Method overloading is performed within class.
