hi Wickes:
Sun documentation refers to ArrayList, HashMap, and HashSet as being the preferred "primary implementations". Their overall performance is better, and
you should use them unless you need a special feature provided by another implementation. In general, Vector is slower because all of its methods are sync. Regular array are lighter wieght than any other collection class. If you find arrays fit your needs, you should consider them first, otherwise you should looke for the appropriate collection calss.
