Can interfaces be implemented in classes?

Can interfaces be implemented in classes?

Yes, interfaces can be implemented in classes. In many programming languages, a class can implement one or more interfaces, which allows it to define the methods specified by those interfaces.

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

An interface defines a contract that implementing classes must follow, while an abstract class can provide some method implementations and state.

Can a class implement multiple interfaces?

Yes, a class can implement multiple interfaces, allowing it to inherit behaviors from multiple sources.

Are there any limitations to using interfaces?

One limitation is that interfaces cannot contain any implementation code (in some languages), only method signatures.

Can you give an example of an interface in a programming language?

Sure! In Java, you might define an interface like this: public interface Animal { void makeSound(); } and then implement it in a class.
