Well you could write your own JSON parser, but there's no need to re-invent the wheel - there are a number of robust, mature JSON parsers freely available. I use JSONObjectand JSONArrayfrom Tapestry. If you downloadTapestry 5 and unpack it, then just include the library tapestry-core-5.0.18.jarin your build path and you'll be set to go. Both JSONObject and JSONArray take a String as constructor argument, and the api is fully documented in those links.
好吧，您可以编写自己的 JSON 解析器，但无需重新发明轮子 - 有许多免费提供的强大、成熟的 JSON 解析器。我使用 Tapestry 的JSONObject和JSONArray。如果您下载Tapestry 5 并解压缩它，那么只需将库包含tapestry-core-5.0.18.jar在您的构建路径中，您就可以开始使用了。JSONObject 和 JSONArray 都采用 String 作为构造函数参数，并且这些链接中完整记录了 api。

使用http://json-lib.sourceforge.net/真的很容易。
See http://json-lib.sourceforge.net/snippets.html
见http://json-lib.sourceforge.net/snippets.html
String str = "{'dealerName':'NPD STATION SDN BHD', 'dealerID': 1, 'dealerReputation': 2.0, 'dealerActive': true}";
JSONObject jsonObject = (JSONObject) JSONSerializer.toJSON( str );
and
和
String str = "['NPD STATION SDN BHD', 1, 2.0, true]";
JSONArray jsonArray = (JSONArray) JSONSerializer.toJSON( str );
