It so happens i got it before someone else had a chance to help. In case someone else has similar question, i am posting an answer below:
碰巧我在别人有机会帮助之前就得到了它。如果其他人有类似的问题，我在下面发布答案：
JSONObject o = new JSONObject(s);
JSONArray arrayOfTests = (JSONArray) ((JSONObject) o.get("Groups")).get("Test");
for (int i = 0; i < arrayOfTests.length(); i++) {
System.out.println(arrayOfTests.get(i));
}
