Sorting a Map

[Hind]

Hi,

How can I sort a map by value, the following code sort it in a list but the map remain unsorted:

Set entries = map.entrySet();
List entryList = new ArrayList(entries);
Collections.sort(entryList, new Comparator() {
     public int compare(Object o1, Object o2) {
          MapEntry me1 = (MapEntry)o1;
          MapEntry me2 = (MapEntry)o2;
          return ((Comparable)me2.getValue()).compareTo(me1.getValue());
     }
});

Thanks in Advance,
Hind
