Collections which iterate bi-directionally?

[yamini nadella]

I read ArrayList iterate bi-directionally. what other collections iterate bi-directionally?

[Eric Pramono]

Based on the API, I think that ArrayList, LinkedList & Vector have the listIterator() method which allows them to return a ListIterator representation of the collection data.
The ListIterator interface methods are the ones that actually allow the data to read in reversed order (using previous() method).
BTW, is this a part of the 1.4 exam?
