Java에서 JSON 배열 객체에 어떻게 액세스하고 처리합니까?

{
  "locations": {
    "record": [
      {
        "id": 8817,
        "loc": "NEW YORK CITY"
      },
      {
        "id": 2873,
        "loc": "UNITED STATES"
      },
      {
        "id": 1501
        "loc": "NEW YORK STATE"
      }
    ]
  }
}

JSONArray recs = req.getJSONObject("locations").getJSONArray("record");

for (int i = 0; i < recs.length(); ++i) {
    JSONObject rec = recs.getJSONObject(i);
    int id = rec.getInt("id");
    String loc = rec.getString("loc");
    // ... (Process the data as needed)
}
