You use function overriding in Java when you inherit a bunch of features from a class and for a few particular cases alone, you do not wish to use the functionality of the parent class and wish to implement a custom feature in your class. In such cases, you create a method in your class with the same name and signature as in your parent class, thereby overloading it. this way only your current class will be used by the JVM unless specifically invoked by using the super keyword.
