• Method Overriding: Occurs when a subclass provides a specific implementation of a method that...read more

• Definition: An abstract class serves as a blueprint for other classes, containing abstract methods that must be implemented by subclasses.

• Cannot be Instantiated: You cannot create an instance of an abstract class directly; it must be subclassed first.

• Abstract Methods: These are methods declared in an abstract class...read more
