Inheritance
It is a process of inheriting (reusing) class members (variables and methods) from one class to another.
The class where the class members are getting inherited is called Parent/Super/Base class
The class to which the class members are getting inherited is called Child/Sub/Derived class
The inheritance between parent class and child class is achieved using the 'extends' keyword
