If you want to go that way but Set extends Collection http://publib.boulder.ibm.com/infocenter/wsadhelp/v5r1m2/index.jsp?topic=/com.sun.api.doc/java/util/Set.html
Collection supports iterator() method which returns an iterator() Iterator iterator()which you can use to iterate thru the collection Iterator iterator = MySet.iterator() http://publib.boulder.ibm.com/infocenter/wsadhelp/v5r1m2/index.jsp?topic=/com.sun.api.doc/java/util/Set.html e.g. while (iterator.hasNext()) { Object obj = iterator.next(); } ?
