Explain final class, abstract class and super class.

A final class cannot be extended. A final class implicitly has all the methods as final, but not necessarily the data members.

An abstract class is a class that is declared by using the abstract keyword. It may or may not have abstract methods. Abstract classes cannot be instantiated, but they can be extended into sub-classes.

Superclass allows various subclassed objects to share certain things in common.It allows: 1)to introduce better data analysis, 2)reduction in development time, 3)less coding efforts, 4)better performance.
