In order to have this result: {"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]} that holds the same data as: { "aoColumnDefs": [ { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] }, { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] }, { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] } ] } you could use this code: JSONObject jo = new JSONObject(); Collection<JSONObject> items = new ArrayList<JSONObject>();   JSONObject item1 = new JSONObject(); item1.put("aDataSort", new JSONArray(0, 1)); item1.put("aTargets", new JSONArray(0)); items.add(item1); JSONObject item2 = new JSONObject(); item2.put("aDataSort", new JSONArray(1, 0)); item2.put("aTargets", new JSONArray(1)); items.add(item2); JSONObject item3 = new JSONObject(); item3.put("aDataSort", new JSONArray(2, 3, 4)); item3.put("aTargets", new JSONArray(2)); items.add(item3);   jo.put("aoColumnDefs", new JSONArray(items));   System.out.println(jo.toString());
