Explanation of Solution
“abstract”:
“abstract” is a keyword or modifier, which is used in the case of class and method.
Purpose of “abstract” class:
An “abstract” class is a class which may or may not include abstract methods and cannot be instantiated, but rather can be sub classed or it must serve as a superclass.
The conditions for a class to be considered as legal “abstract” class are mentioned below:
- If a class includes “abstract” methods, then the class must be declared as “abstract”...
