public class Main {
   public static void main(String[] args) {
      TreeMap<Integer, String>  treemap = new TreeMap<Integer, String> ();
      // populating tree map
      treemap.put(2, "two");
      treemap.put(1, "one");
      treemap.put(3, "three");
      treemap.put(6, "six");
      treemap.put(5, "from");   
      // polling last entry
      System.out.println("Value before poll: "+ treemap);            
      System.out.println("Value returned: "+ treemap.pollLastEntry());      
      System.out.println("Value after poll: "+ treemap);

The code above generates the following result.
