This question can also be asked in a slightly different way
Give an example of where we could use an abstract class?
Let us understand when to use an abstract class with an example. An organisation has 2 types of employees
1. FullTimeEmployee
2. ContractEmployee
We would create an abstract class, when want to move the common functionality of 2 or more related classes into a base class and when, we don’t want that base class to be instantiated.
