Method Overloading vs Method Overriding in Object-Oriented Programming

Method overloading and method overriding are important concepts in object-oriented programming that involve the use of methods in classes. Here is a breakdown of the key differences between the two:

Method Overloading:

Method overloading occurs when there are multiple methods in a class with the same name but different parameters. This allows the same method name to be used for different actions based on the parameters passed to it. The compiler determines which method to execute based on the number and type of parameters provided.

Method Overriding:

Method overriding, on the other hand, involves creating a new implementation for a method in a subclass that is already present in its superclass. This means that the method in the subclass has the same name and signature as the method in the superclass, thus replacing the original implementation with the new one. When the method is called in the subclass, the overridden implementation is executed instead of the one in the superclass.

Overall, method overloading is achieved within the same class with different parameters, while method overriding is used in inheritance to provide a new implementation for a method in a subclass.
