What are the advantages 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 various sources without the complexities of multiple class inheritance.

What is the difference between an interface and an abstract class?

An interface can only declare methods without implementation, while an abstract class can have both abstract methods and concrete methods.

How do interfaces improve code maintainability?

Interfaces allow for a clear contract for classes, making it easier to change implementations without affecting the code that uses them.

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.
