What is an abstract class?..

Answer / prasviji143@gmail.com

abstract class is an incomplete class which contains incomplete and complete methods.

incomplete methods contains only the declaration and ended with semicolon (; )

To access the incomplete methods we need create a concrete class with the help of extends keyword.

In concrete class there will be method definitions for incomplete methods.

abstract class is known as superclass and concrete class as subclass.


In concrete class we can create the object and we can call the incomplete methods and execute the program.
