本文通过一个具体的示例展示了如何使用Java处理JSON字符串。其中包括创建JSONObject对象、遍历键值对等基本操作。

String s="{"error":"0","msg":"读取成功","addressjson":[{"id":"3","name":"成龙","p":"130000","c":"130300","d":"130321","address":"在哪里","zcode":"58888","phone":"1366815555","def":"0"}]}";

                try {
                    JSONObject obj= new JSONObject(s);

                    Iterator it = obj.keys();
                String vol = "";//值
                    String key = null;//键
                    while(it.hasNext()){//遍历JSONObject
                        key = (String) it.next().toString();
                       vol = obj.String(key);
                       

                    }
                   
                } catch (JSONException e) {
                    e.printStackTrace();
                }
