Is it compulsory to have atleast one abstract method in
abstract class?

Answer Posted / saurabh m. chande

It is absolutely not necessary to have at-least 1 method as an abstract method in a class which is defined as an abstract.
But it is equally necessary to declare the class as an abstract class if at-least 1 method within that class is declared as abstract method.
Abstract class contains either the method declaration only or complete method implementation.
