I can’t figure out a use case for being able to annotate interfaces in Java.
Maybe someone could give me an example?

I’ve used it in Spring to annotate interfaces where the annotation should apply to all subclasses. For example, say you have a Service interface and you might have multiple implementations of the interface but you want a security annotation to apply regardless of the annotation. In that case, it makes the most sense to annotate the interface.
