I have a question about Collection: which classes allow unsynchronized read operations by multiple threads in the Collection Hierarchy ? Can some similar questions appear in the real exam? [ May 28, 2003: Message edited by: Lei Zheng ]
hi, in my knowledge all classes except Vector and Hashtable, allow non-synchronized access. Vector and Hashtable are thread-safe. just to mention, we can get synchronized 'version' of new Collection family too. for instance, Set s = Collection.synchronizedSet(new TreeSet());
