        JSONObject object = new JSONObject();
        try {
            // create multiple object
            JSONObject obj1 = new JSONObject();
            obj1.put("targetId", 1);
            obj1.put("celsius", 34.5);
            obj1.put("measuredTime", "2021-03-25,11:40:01");
            obj1.put("isFirst", true);

            // add all created object in array
            JSONArray array = new JSONArray();
            array.put(obj1);

            // add array in main object
            object.put("infos" , array);
        } catch (JSONException e) {
            e.printStackTrace();
        }
