You can download Java (JDK5 or later) and have a look at class ConcurrentHashMap. This will give you a blueprint about how this can be implemented using segments. After segment lookup for a given hash code only the segment needs to be locked, but not any more the entire map. Note, that you still have to lock the entire map when you do traversals. So it is recommend to avoid traversals where possible.
