import java.util.Iterator;
import java.util.TreeSet;

/*
 * Example of descendingIterator() method.
 */
public class TreeSetExample
{
    public static void main( String[] args )
    {

        TreeSet<Integer> treeSet = new TreeSet<Integer>();

        treeSet.add(40);
        treeSet.add(20);
        treeSet.add(30);
        treeSet.add(10);
        treeSet.add(50);

        System.out.println("treeSet : " + treeSet + "\n");

        /*
         * Returns an iterator over the elements in this set in descending
         * order.
         */

        Iterator<Integer> iterator = treeSet.descendingIterator();
        while( iterator.hasNext() )
        {
            Integer value = (Integer) iterator.next();
            System.out.println(value);

        }
    }
}

Output

treeSet : [10, 20, 30, 40, 50]

50
40
30
20
10
