Inheritance
Get familiar with the concept of inheritance and its type with implementation.
Definition
Inheritance provides a way to create a new class from an existing class. The new class is a specialized version of the existing class such that it inherits all the public attributes (variables) and methods of the existing class. The existing class is used as a starting point or base to create the new class.

After reading the definition above, the next question that comes to mind is, “when do we use inheritance?” Wherever we come across an IS-A relationship between objects, we can use inheritance.
