Question
Abstract class?
Answers
An abstract class is a class which can’t be instantiated (we cannot create the object of abstract class), we can only extend such classes. It provides the generalized form that will be shared by all of its subclasses, leaving it to each subclass to fill in the details. We can achieve partial abstraction using abstract classes, to achieve full abstraction we use interfaces.   Your Comment
