What is an Abstract Class?

An abstract class is a class that cannot be instantiated directly. It serves as a blueprint for other classes and may include abstract methods, which must be implemented by derived classes.

Key Point: Abstract classes can include both fully implemented methods and methods that are only declared (abstract methods).
