Unable to construct JSON response in this format

I need to construct JSON response in this format

{
   label : "name",
   items : [
       {name : "Name1"},
       {name : "Name2"}
   ]
}

Inside my Servlet program i used this way

List list = new ArrayList();

        for (int i = 0; i <= 10; i++) {
            list.add("Test");
        }

        JSONObject json = new JSONObject();
        json.put("label", "name");
        json.put("items", list.toArray());

 开发者_Python百科       response.getWriter().write(json.toString());

With this format , When i checked Firebug , the response is coming this way :

{"label":"name","items":["Test","Test","Test","Test","Test","Test","Test","Test","Test","Test","Test"]}

Please tell me how to construct in this format .

You have to create the objects inside the Array. This should work:

List list = new ArrayList();

for (int i = 0; i <= 10; i++) {
    JSONObject nextObject = new JSONObject();
    nextObject.put("name", "Name" + i);
    list.add(nextObject);
}

JSONObject json = new JSONObject();
json.put("label", "name");
json.put("items", list.toArray());

response.getWriter().write(json.toString());

One thing that i want say that in the json data you wanted is a data structure where we need to put json object to the list and then put the list to a json object referance. I think this link will help you.
