ArrayList question

[Guest_imported]

Hello;

I have a couple of questions about the ArrayList collection.

1. Are they kept in a sorted order?
2. If they aren't, is it possible to keep one sorted? while inserting objects?

Thanks!

No the ArrayList is not guaranteed to be in sorted order. It will be in whatever order the items are entered. You can always sort an ArrayList though. If you want a Collection that has guaranteed sorted order (when accessed the proper way using an Iterator) then you should look to using a SortedSet. Of course a SortedSet has the added restriction of not allowing duplicate entries.
