public static void testMapVoid () {
  Map map = new HashMap();
  map.put("a", "a1");
  map.put("b", "b1");
  map.put("c", "c1");

  List listKey = new ArrayList();
  List listValue = new ArrayList();
  Iterator it = map.keySet().iterator();
  while (it.hasNext()) {
    String key = it.next().toString();
    listKey.add(key);
    listValue.add(map.get(key));
  }
  System.out.println("Convert Finished !");

  for(int i =0 ;i<listKey.size();i++){
    System.out.print("Key :"+listKey.get(i));
    System.out.println(" Value :"+listValue.get(i));
