i'll tell u what ive been doing so far.. Ive got 3 classes, 1) Person (interface extends Comparable) 2) ThePerson (implements Person) 3) PersonList (TreeSet holds collection of Person class)
the Persons will be sorted based on their ID numbers.. so this should be done automatically because im using TreeSet, is this correct?
Now, i want the collection to be slso sorted using another attribue that is "name", iv got a comparator ready to do that, but i cant use
collections.sort(treeSet, comp) <-- because its a Set!!
can some1 please please help me out Hannah

Look at the TreeSet constructors. Can you see a way to make a new TreeSet sorted by a comparator using the original for data? [ July 28, 2005: Message edited by: Stan James ]
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

Yup, but I think you're out of luck. Constructing a new one is not that big a deal as long as you kept the variable private so nobody is holding a reference to the old one.
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
