treeset

Here is the piece of code that I have used for Java 5.0

TreeSet<Integer> treeSetObj = new TreeSet<Integer>( Collections.reverseOrder() ) ;

Collections.reverseOrder() is used to obtain a comparator in order to reverse the way the elements are stored and iterated.

Is there a more optimized way of doing it?
