3. Conversion

　　　　　String listUsers = userClient.listUsers();        JSONArray jArray= JSONArray.fromObject(listUsers);        Collection collection = JSONArray.toCollection(jArray, User.class);        List<User> userList = new ArrayList<User>();        Iterator it = collection.iterator();        while (it.hasNext()) {            User user = (User) it.next();            userList.add(user);        }
