An interface is typically used in place of an abstract class when there is no default implementation to inherit.

Interface only provides the signature or the blueprint for the methods, and the implementing classes are required to provide the actual implementation. There is no default implementation provided in an interface, which is why it is used when there is no default implementation to inherit. Abstract classes, on the other hand, can provide default implementations for some or all of their methods.
