JSON - Map data Order issue

Question

Hi,
I am creating a JSON Object from the following code...Code is creating JSON perfect but not prinitng in order in which i am entering the data see below the output
JSONArray product = new JSONArray();
JSONObject jsonObj = null;
while (iterator.hasNext())
                msg=(Product)iterator.next();
                map = new HashMap();
                         map.put("id", msg.getId());
                map.put("description", msg.getDescription());
                map.put("price", msg.getPrice());
                map.put("category", msg.getCategory());
                jsonObj= new JSONObject(map);
                jsonArray.put(jsonObj);
Actual Output
{"price":5.75,"description":"Lamp","category":"Accessories","id":"AA0079456BK"}
Expected Output
{"id":"AA0079456BK","description":"Lamp","price":5.75,"category":"Accessories"}
I have tried both Hashmap and TreeMap but same result....MAP is not returning the value in order in which i am entering the data..
I also tried LinkedHashMap() but same issue exist wheras if i try to print value using iterator it prints in correct order
for (Iterator it=map.keySet().iterator(); it.hasNext(); ) {
                  Object key = it.next();
                  Object value = map.get(key);
                  System.out.println(key +"="+value);
Output
id=AP98784511K
description=Sofa
price=22.79
category=Living
Please help..
Regards,

Answer 1

In all cases returning iterator is a bad way to get order of objects what You expected!
Try to store them into ArrayList<BaseObject> . The BaseObject would store title and obect pair(Ex "description" and msg.getDescription()).
And then simply call arraylist.add(BaseObject).
In second loop get your expected value as arraylist.get(i) .
