[java] How can I iterate JSONObject to get individual items

This is my below code from which I need to parse the JSONObject to get individual items. This is the first time I am working with JSON. So not sure how to parse JSONObject to get the individual items from JSONObject.

try {
    String url = service + version + method + ipAddress + format;
    StringBuilder builder = new StringBuilder();
    httpclient = new DefaultHttpClient();
    httpget = new HttpGet(url);
    httpget.getRequestLine();
    response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();
    if (entity != null) {
        InputStream inputStream = entity.getContent();
        bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        for (String line = null; (line = bufferedReader.readLine()) != null;) {
            builder.append(line).append("\n");
        }
        JSONObject jsonObject = new JSONObject(builder.toString());
        // Now iterate jsonObject to get Latitude,Longitude,City,Country etc etc.

    }

} catch (Exception e) {
    getLogger().log(LogLevel.ERROR, e.getMessage());
} finally {
    bufferedReader.close();
    httpclient.getConnectionManager().shutdown();
}

My JSON looks like this:

{
    "ipinfo": {
        "ip_address": "131.208.128.15",
        "ip_type": "Mapped",
        "Location": {
            "continent": "north america",
            "latitude": 30.1,
            "longitude": -81.714,
            "CountryData": {
                "country": "united states",
                "country_code": "us"
            },
            "region": "southeast",
            "StateData": {
                "state": "florida",
                "state_code": "fl"
            },
            "CityData": {
                "city": "fleming island",
                "postal_code": "32003",
                "time_zone": -5
            }
        }
    }
}

I need to get latitude, longitude, city, state, country, postal_code from the above object. Can anyone provide any suggestion how to do it efficiently?

The answer is


How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"
