                JSONObject results =jsono.getJSONObject("results");
                JSONArray result =results.getJSONArray("result");



            } catch(JSONException ex) {
                System.out.println("Exception thrown: " + ex.getMessage());

您需要在库中包含Json jar。

从这里下载ZIP文件并解压缩它以获得jar。将Jar添加到构建路径中。要检查这个Jar中可用的类，请使用这个URL。

将此Jar添加到构建路径

Right click the Project > Build Path > Configure build path> Select Libraries tab > Click Add External Libraries > Select the Jar file Download
