這是我正在使用的 json。我需要打印數(shù)組description內(nèi)的對(duì)象weather。JSONArray[2] not found編譯時(shí)出現(xiàn)異常。我正在使用 java-json。{  "coord": {    "lon": 72.85,    "lat": 19.01  },  "weather": [    {      "id": 721,      "main": "Haze",      "description": "haze",      "icon": "50n"    }  ],  "base": "stations",  "main": {    "temp": 303.15,    "pressure": 1009,    "humidity": 74,    "temp_min": 303.15,    "temp_max": 303.15  },  "visibility": 3000,  "wind": {    "speed": 2.1,    "deg": 360  },  "clouds": {    "all": 20  },  "dt": 1539273600,  "sys": {    "type": 1,    "id": 7761,    "message": 0.0642,    "country": "IN",    "sunrise": 1539219701,    "sunset": 1539262109  },  "id": 1275339,  "name": "Mumbai",  "cod": 200}這是代碼——import java.io.BufferedReader;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;import org.json.JSONObject;import org.json.JSONArray;class Send_HTTP_Request2 {    public static void main(String[] args) {     try {         Send_HTTP_Request2.call_me();        } catch (Exception e) {         e.printStackTrace();       }     } static void call_me() throws Exception {     String url = "http://api.openweathermap.org/data/2.5/weather?id=1275339&APPID=77056fb4e0ba03b117487193c37c90d2";     URL obj = new URL(url);     HttpURLConnection con = (HttpURLConnection) obj.openConnection();     int responseCode = con.getResponseCode();     System.out.println("\nSending 'GET' request to URL : " + url);     BufferedReader in = new BufferedReader(             new InputStreamReader(con.getInputStream()));     String inputLine;     StringBuffer response = new StringBuffer();     while ((inputLine = in.readLine()) != null) {        response.append(inputLine);     }     in.close();     JSONObject myResponse = new JSONObject(response.toString());         JSONArray jrr= myResponse.getJSONArray("weather");          System.out.println("CITY-"+myResponse.getString("name"));         JSONObject desc = jrr.getJSONObject(2);         System.out.println(desc);}}
