How to Convert JSON String arrray to Json Array list


I have Json String array ,which looks like this ,

{ {name:"214",value:true,Id:0},
  {name:"215",value:true,Id:0},
  {name:"216",value:true,Id:0}
}

and want to covert this string to Json array object and iterate the list to read each object's value. Then set values to corresponding dto and save it . But i didnt find any good way to convert normal JSON array string to json array object.

I am not using google json , I want it to be done in normal json itself .Please help me

and java class i want something like this

JSONObject[] jsonObjectList = String after convert();

    for (JSONObject jsonObject : jsonObjectList) {
        System.out.println(" name is --"+jsonObject.get("name"));
        System.out.println(" value is ---"+jsonObject.get("value"));
        System.out.println(" id is ----"+jsonObject.get("id"));

    }

Solution

  • Here is the example for parsing json Object.. use JSON lib for this..

    import net.sf.json.JSONArray;
    import net.sf.json.JSONException;
    import net.sf.json.JSONObject;
    import net.sf.json.JSONSerializer;
    public class TestJson {
        public static void parseProfilesJson(String jsonStr) {
            try {
                JSONArray nameArray = (JSONArray) JSONSerializer.toJSON(jsonStr);
                System.out.println(nameArray.size());
                for(Object js : nameArray){
                    JSONObject json = (JSONObject) js;
                    System.out.println(json.get("date"));
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
        public static void main(String[] args) {
            String s = "[{\"date\":\"2012-04-23\",\"activity\":\"gym\"},{\"date\":\"2012-04-24\",\"activity\":\"walking\"}]";
            parseProfilesJson(s);
        }
    }
