import java.util.*;
public class TreeMapDemo
{ public static void main(String[] args)

TreeMap<Integer, String> treemap = new TreeMap<Integer, String>();

  treemap.put(2, "two");
treemap.put(1, "one");
treemap.put(3, "three");
treemap.put(6, "six");
treemap.put(5, "five");

Navigable map nmap=treemap.descendingMap();

  System.out.println(nmap); } }
