Is there a "Set" data structure? (Read 341 times)

Is there a "Set" data structure?
Oct 25th, 2009, 6:46am  
I'm having difficulty figuring out, since the word is so common, if there is any standard implementation for a "Set". You know, the math kind? An unordered collection without repetition? I don't see anything in the reference.. Is there a commonly used library with this object in it?

See Java's Set interface, implemented, among others, by the popular HashSet.
I link to Java 1.4 docs to avoid confusion with the generics not yet allowed in Processing.

Processing's reference doesn't, and cannot, reference all Java's doc (does it for some common stuff like Strings and ArrayList, though), so it is always a good idea to check Java ref.
