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 support multiple inheritance?

Interfaces allow a class to implement multiple interfaces, enabling it to inherit behaviors from multiple sources without the complexities of multiple class inheritance.

What about code maintainability?

Interfaces help in defining a contract for classes, making it easier to modify and maintain code without affecting other parts.

Are there any performance implications?

Generally, using interfaces may introduce a slight overhead due to dynamic method resolution, but the benefits often outweigh this.

Can you give an example of an interface in Java?

Sure! An example is the 'Comparable' interface, which allows objects to be compared to each other, enabling sorting.
