title: change an ascending sort to descending
body: <p>I have the following code to sort a list but I need to make it a descending sort,</p>
  
  <pre><code>List list = new LinkedList(thismap.entrySet());
  Collections.sort(list, new Comparator() {
      public int compare(Object o1, Object o2) {
          return ((Comparable) ((Map.Entry) (o2)).getValue())
                  .compareTo(((Map.Entry) (o1)).getValue());
      }
  });
  
  Map output = new LinkedHashMap();
  for (Iterator it = list.iterator(); it.hasNext();) {
      Map.Entry entry = (Map.Entry) it.next();
      output.put(entry.getKey(), entry.getValue());
  }
  </code></pre>
