Abstraction concept is developed to solve the complexity of programming. Abstraction simplifies the programming by abstracting a class in Object Oriented Programming. If you declare a class Abstract in Java then you would be able to create the object of the that class. To use the definition of the abstract class you have to extend the abstract class in an new class and then implement the abstract method. Then you can create the object of the new class.
