java解析json

请问这种格式的json 数据该怎么解析？ 小弟不才。只会解析简单的 {"A":"A","B":"B"} 这种类型的
{
"result":
{
"rcResponse":
{"List1":["1111","2222","3333"],
"List2":["1111","2222","3333"],
"spotList":["1111","2222","3333"],
"version":"1.1",
"transID":"001112300004560000",
"flag":"1"
},
"resultCode":"0"
}
}

谢谢高手指导

[code="java"]String jsonString = { "result":{"rcResponse": {"List1":["1111","2222","3333"],"List2":["1111","2222","3333"], "spotList":["1111","2222","3333"], "version":"1.1", "transID":"001112300004560000", "flag":"1" }, "resultCode":"0"} };

JSONObject jsonObj = JSONObject.fromObject(jsonString);

JSONObject result = jsonObj.getJSONObject("result");
JSONObject rcResponse = result.getJSONObject("rcResponse");
JSONArray list1=jsonObj.getJSONArray("List1");
JSONArray list2=jsonObj.getJSONArray("List2");

System.out.println("list1[0]:"+list1.get(0));

JSONObject version= result.getJSONObject("version");

System.out.println("obj:"+obj.get("firstName")); [/code]

应该是[ 开头的 就用getJSONArray，普通的{开头就getJSONObject
