How can i get the first url in this json file ? What I have so far is: 

                JSONObject file = (JSONObject) files.get(j);

                String url = (String) file.get("url");
                System.out.println(url);

  • Aside from "Don't use that ancient crufty json.org library" there are *numerous* examples of parsing JSON in Java here on SO that would get you further than you are. – Brian Roach Jun 15 '13 at 23:52

  • currently am getting the two url but i can't figure out how to get just the first url in the file. I don't know if there is something like `.first()`? – fumzy Jun 15 '13 at 23:56

  • you can fetch this files object as a JSONArray instead of JSONObject. The advantage being that, you get array.get(index) method for the JSONArray. – voidMainReturn Jun 16 '13 at 00:09

something like this should work :

JSONArray results = d.getJSONArray("files");
JSONObject p = (JSONObject)results.get(0);
url = p.getString("url");
