use
Gson gson = new GsonBuilder().create();

JsonArray myCustomArray = gson.toJsonTree(list).getAsJsonArray();

You can use org.codehaus.jettison.json.JSONArray for the same (Download jar).

Example Code :

   ArrayList bibo=new ArrayList();

   .....

  JSONArray ar=new JSONArray(bibo);
  String json= ar.toString();

Use GSON library for that. Here is the sample code

ArrayList<String> bibo = new ArrayList<String>();
bibo.add("obj1");
bibo.add("obj2");
bibo.add("obj3");
String json = new Gson().toJson(bibo);

And this example from Gson User Guide to use it on collection
