The throws clauses about Exceptions in the interface's methods must exactly match the throws clauses of the implementing methods. That means, we can't even declare the implemented methods as subclass of that Exception. Please confirm, I got it from a Note. Thanks in Advanced!~

In K&B's book, It's said that, A nonabstract implementing class must not declare any new checked exceptions for an implementation method. That means, We can't declare a subclass type Exception in the method declaration. Please confirm!
An implementation cannot throw new checked exceptions or broader checked exceptions. An implementation can as Neha demonstrated with her example throw a smaller exception (FileNotFoundException vs IOException). Of course can an implementation throw new RuntimeExceptions (lowercase T).
