- Explain why you think interfaces are better than abstract classes in your opinion.Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methodsAbstract classes, abstract methods and Interfaces are three important OOP concepts. Give an example where each would be appropriate to use
- What are the fundamental differences between an abstract classes and interface?What are the major differences between abstract classes and interfaces?Classes at the abstract level and interfaces at the implementation level may both be used to describe the same kinds of behavior in different objects.What criteria should you use to choose between using an interface and an abstract class?
