Inheritance is one of the most important object-oriented programming concept.
Inheritance allows to derive a new class from an existing class.
Inheritance allows user to define the new class with the characteristics of the existing class which is already defined.
Using inheritance, the methods in the super class can redefine in subclass by using a reference variable that address the superclass objects.
The redefined methods can have different implementation in subclass from base class.
When the super class addressed, the method has original implementation.
When the subclass addressed, the method has a new and different implementation.
Using a single reference variable to call the same named methods that are behaving differently called polymorphism.
