no get in tree set?

| It appears that TreeSet has no object retrieval method. Am I overlooking
something? I probably neet to use TreeMap? I need a collection which will
be filled once, with items rarely being added or removed. But access to the
items in the list will often be random, as opposed to sequential. Is
TreeMap the best choice?
Thanks,

There's no *indexed* retrieval because it's a set, not a map. You can test
for inclusion in the set (contains(o)) or you can iterate through the items
if you like (iterator, first, last, etc). If you want indexed access, you
need some kind of Map.
