> json格式如下：{"response":{"data":[{"address":"南京市游乐园","province":"江苏","district":"玄武区","city":"南京"}]},"status":"ok"}
Result： 江苏 南京 玄武区 南京市游乐园

JSONObject dataJson=new JSONObject("Json data");
JSONObject response=dataJson.getJSONObject("response");
JSONArray data=response.getJSONArray("data");
JSONObject info=data.getJSONObject(0);
String province=info.getString("province");
String city=info.getString("city");
String district=info.getString("district");
String address=info.getString("address");
System.out.println(province+city+district+address);
