Answer / naveen kumar
Abstract classes are classes that contain one or more abstract methods. Abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.

An abstract class is a template definition of methods and variables of a class (category of objects) that contains one or more abstracted methods. ... Declaring a class as abstract means that it cannot be directly instantiated, which means that an object cannot be created from it.
