JSON数据转对象遍历

        String json = "[{\"n\":\"北京\",\"i\":11,\"p\":0,\"y\":\"b\"},{\"n\":\"北京\",\"i\":1101,\"p\":11,\"y\":\"b\"}]";
        JSONArray jsonArray = JSONArray.parseArray(json);

        for (Object value : jsonArray) {
            JSONObject serverEntryObj = (JSONObject)  value;
            System.out.println(serverEntryObj.getString("n"));
        }
