Using Gson Library it will be very simple.

From JSON String to ArrayList of Object as:

Type listType = 
     new TypeToken>(){}.getType();
ArrayList yourClassList = new Gson().fromJson(jsonArray, listType);

And to Json from Array List of Object as:

ArrayList sampleList = new ArrayList();
String json = new Gson().toJson(sampleList);

The Gson Library is more simple to use than JSONObject and JSONArray implementation.
