Can you explain the implementation of abstract classes and interfaces in inheritance, as well as the concepts of function overloading and overriding?

Question

Accepted Answer

Abstract classes and interfaces in inheritance allow for defining common behavior and function signatures, while function overloading and overriding enable polymorphism.

Abstract classes are classes that cannot be instantiated and may contain abstract methods that must be implemented by subclasses.
Interfaces are similar to abstract classes but can only contain method signatures and constants, with no method implementations.
Function overloading refers to having multiple methods with the same name but different parameters in a class.
Function overriding occurs when a subclass provides a specific implementation for a method that is already defined in its superclass.
