Both abstract classes and interfaces are important concepts in object-oriented programming, however they both have different roles that create distinctions between the two. An abstract class is a class which provides a partial implementation of its parent or grandparent classes. On the other hand, an Interface defines methods and constants that must be implemented by any class that implements it.

What is an abstraction class?
An abstract class is a special type of class which provides a partial implementation of its parent or grandparent classes and cannot be instantiated, but can be extended.
What does an interface do?
Interfaces define methods and constants that must be implemented by any class that implements them. These methods and constants act as contracts between objects and define how they interact with each other.
How do abstraction classes and interfaces differ?
Abstract classes provide partial implementations while interfaces define what objects must implement in order to interact with each other. Additionally, abstract classes can contain defined variables while interfaces cannot.
Can an interface extend an abstract class?
No, an interface cannot extend an abstract class because both define different types of structures for developers to use when building their applications. Interfaces require full implementations while abstract classes provide partial ones, so extending does not make sense in this case.
Conclusion:
In conclusion, both abstraction classes and interfaces play distinct roles in object-oriented programming by providing developers with different ways to structure their code and designs.
