Answer 3

Collection is just an interface, extended by other interfaces like List and Set (which both have multiple concrete implementations)

You may use the Collection-Type for your varaiable if you want to be completely decoupled from the concrete type, if you want to have some extra constraints (like unique values only) you set your variable to Set. You can pass your set to any method that wants a xollection, but you can not pass a collection to a method that wants to get a Set as argument.

Just read a little bit about lose coupling in java...
