Answer Posted / madhusudhanreddy t
Abstract is a keyword which can be used with methods and classes. When ever a class is not providing the full functionality then it is recommended to declare that class as the abstract class. When a class contains at least one abstract method then that class must be declared as abstract.
Abstract classes provide set of rules (abstract methods) which must be followed (overided) in the derived classes.
Abstract classes are not instantiable,but a reference can be created.
