I have a question about those two interfaces in Java. Set extends Collection, but doesn't add anything. They are exactly the same. Am I missing something here ?

Set doesn't allow duplicates. It's a semantic difference, not a syntactic one.

Collection<E> and Set<E> are the same?

Set doesn't allow duplicates.
