What are interfaces in programming?
Interfaces in programming define a contract that classes can implement. They specify methods that must be created.
Can you give me an example of an interface?
Sure! In Java, an interface might look like this: public interface Animal { void makeSound(); }
.
How do interfaces differ from abstract classes?
Interfaces can only declare methods without implementation, while abstract classes can have both abstract and concrete methods.
Why would I use an interface instead of a class?
Using interfaces allows for multiple inheritance and helps in defining a common behavior across different classes.
