2You can print the Sorted HashMap values using the following way:
          HashMap map = new HashMap();
          map.put("1","First");
          map.put("2","Second");
          map.put("3","Third");
          ArrayList keys = new ArrayList();
          keys.addAll(map.keySet());
          Collections.sort(keys);
          Iterator it = keys.iterator();
          while (it.hasNext())
          System.out.println(it.next());
Refer the outcome keys, and print the HashMap values, thats all.
