Answer Posted / madipally naveen kumar

Abstract Class is a class , in which at least one method is
declared as abstract.Abstract method is a method for which
implementation is not provided in that class.This method
can be implemented by the classes which inherited the
Abstract class and we can not instantiate the abstract
class.Abstract classes can be used when we want to
partially leave certain methods for inheriting classes to
implement.
