        Greetings!
I have a question concerning removing duplicate objects from two (combined) arrays:

Hi!

We do something similar to this and we also use Sets for this (not NSSet but HashSet, I'm not sure if that matters)

Our code which so far seems to work ok:

                List l1 = Arrays.asList(questionsFromQText.objects());
                List l2 = Arrays.asList(questionsFromAText.objects());
                HashSet hs = new HashSet();
                hs.addAll(l1);
                hs.addAll(l2);
                questions = new NSArray(hs.toArray());

-Kaj :)
