What are the benefits of using interfaces in Java?

What are the benefits of using interfaces in Java?

Using interfaces in Java promotes abstraction, allows multiple inheritance, and enhances code flexibility and maintainability.

Can you explain how interfaces promote abstraction?

Interfaces allow you to define methods without implementing them, enabling different classes to provide their own implementations.

What do you mean by multiple inheritance?

In Java, a class can implement multiple interfaces, allowing it to inherit behaviors from multiple sources, unlike class inheritance.

How do interfaces improve code maintainability?

Interfaces help in decoupling code, making it easier to modify or replace implementations without affecting other parts of the code.

Are there any downsides to using interfaces?

While interfaces offer many benefits, they can add complexity and may lead to over-engineering if not used judiciously.
