What is inheritance?
Inheritance is a functionality of object-oriented programming where a subclass obtains the contents and functionality of its superclass.
Instead of duplicating a class, a user can create a class that is a subclass of another class, inherit all of its functionality, and just add additional functionality.
For example, if the class "Bike" already exists and we wanted to create specific type of bicycle such as "MountainBike" or "RoadBike", we could just create classes that inherit from the "Bike" class and add the additional functionality we need.
