    their is no difference abstract and abstract class
    Abstract class:
    Abstract classes are classes that contain one or more abstract methods (methods without implementation). An abstract method is a method that is declared, but doesn't contain implementation (like method declaration in the interface). Abstract classes can't be instantiated, and require subclasses to provide implementations for the abstract methods. This class must be inhertied. This class is mostly used as a base class.
