What are the advantages of using interfaces in programming?

What are the advantages of using interfaces in programming?

Using interfaces allows for better abstraction, code reusability, and easier maintenance. They define a contract for classes.

Can you explain how they improve code reusability?

Interfaces enable different classes to implement the same methods, allowing for interchangeable components and reducing code duplication.

What about their role in polymorphism?

Interfaces are key to achieving polymorphism, as they allow objects of different classes to be treated as objects of a common interface type.

Are there any downsides to using interfaces?

One downside is that they can add complexity to the codebase, especially if overused or if the interface design is not well thought out.
