      TreeMap<Integer, String>  treemap = new TreeMap<Integer, String> ();
      TreeMap<Integer, String>  treemapclone = 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");
      // cloning tree map
      System.out.println("Cloning tree map");
      System.out.println("Original map: "+ treemap);
      System.out.println("Cloned map: "+ treemapclone);

The code above generates the following result.
