In java, you can create a synchronized version of any java standard 
collection . Same collection name, same interface, etc...

see

http://developer.java.sun.com/developer/qow/archive/60/index.html

This is from the above

"The synchronization wrappers add automatic synchronization (thread-safety) 
to an arbitrary collection. There is one static factory method for 
each of the six core collection interfaces:

 public static Collection synchronizedCollection(
                                      Collection c); 
 public static Set synchronizedSet(Set s); 
 public static List synchronizedList(List list); 
 public static Map synchronizedMap(Map m); 
 public static SortedSet synchronizedSortedSet(
                                       SortedSet s); 
 public static SortedMap synchronizedSortedMap(
                                       SortedMap m); 


Each of these methods returns a synchronized (thread-safe) Collection 
backed by the specified collection."
