The class which implements AQuestion
1. should have someMethod which must necessarily be public.
2. should have someMethod which could be "friendly" or public
3. should have someMethod which should not throw any checked exceptions.
4. should have someMethod which cannot be sychronized as sychronized is not in the signature of the interface definition

The answer is 1, 3.
Shouldn't it be 2,3?
Thanks.

A method inside an interface is impicitly abstract and public. when implementing an interface the method can only be implemented as a public class.
