[Advanced-java] Ordered sets?

[Brian.Cain@xxxxxxxxxxxx (Cain Brian-BCAIN1)]

	I've got a question about ordered sets.  I'd like to use a set, that has order, but I don't want to implement a natural ordering of these elements.  I'd prefer to use the order in which they were added to the set (I don't think the elements of the set need to know, nor should know, the order in which they were added).  

	I know the HashSet's iterator comes "in no particular order", but does anyone know if it was implemented such that I'll end up with the results I want anyways?  It seems like a tremendous waste of effort to intentionally entropize a set's order, so I have to imagine that the elements are added in some logical fashion, right?  Is there a set in the JDK that I'm missing out on, that does what I want?
