Using Iterator for TreeSet

Question

I know that a TreeSet is ordered. But does that guarantee that every time I create an iterator, it is going to go through the elements of the collection in the same order (provided that I am not adding/removing any elements)?

Returns an iterator over the elements in this set in ascending order.
