what is abstract class?

Answer Posted / belson g pradeep

Abstract classes are classes that contain one or more abstract methods .An 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.
