Used to define method signatures for a class using abstract methods similar to interfaces.

. But there are many variations between abstract class and interface which are given below. An abstract class is a good choice if you have plans for. An interface specifies methods that classes using the interface must implement.

Both abstract class and Interface cant be instantiated. Abstract classes can be. WORA implies Write Once Run Anywhere.
