What are interfaces and polymorphism in programming?

Can you explain what interfaces are in programming?

Sure! An interface in programming defines a contract that classes can implement. It specifies methods that must be created, but it doesn't provide the implementation.

How does polymorphism relate to interfaces?

Polymorphism allows objects to be treated as instances of their parent class or interface. This means you can call methods on these objects without knowing their specific class.

Can you give me an example of polymorphism with interfaces?

Absolutely! Imagine an interface called 'Animal' with a method 'makeSound()'. Classes like 'Dog' and 'Cat' implement this interface, each providing their own version of 'makeSound()'. When you call 'makeSound()' on an 'Animal' reference, it will execute the appropriate method based on the actual object type.

What are the benefits of using interfaces?

Using interfaces promotes code reusability, flexibility, and easier maintenance. It allows different classes to be interchangeable as long as they implement the same interface.
