Overriding is useful when you want to change the functionality of some method based on a class. For example, by overriding the toString() method of Object class, we can use it with different classes.

Overloading is useful to add flexibility to a method. In general, if you want to create a method that adds two numbers then it only take either integer, double, or float but by overloading, you can add values of all data types.
