ArrayList list = new ArrayList();

HashMap map = new HashMap();

map.put("aaa","111");

map.put("bbb","222");

map.put("ccc","333");

list.add(map);

JSONObject jsonObject = new JSONObject(map);

JSONArray jsonArray = new JSONArray(list);

out.println(jsonObject);

out.println(jsonArray);

out.println(((JSONObject)jsonArray.get(0)).get("aaa")); // 777

이걸 굳이 써야하나.. 그냥 ArrayList, HashMap 으로만 써도 되지 않나?
