Answer 1

Create Current Json String as in Java :

    JSONObject parent = new JSONObject();
    JSONObject subparentone = new JSONObject();

    JSONObject subparenttwo = new JSONObject();

    subparentone.put("child-1", "1");
    subparentone.put("child-2", "2");

    subparenttwo.put("child-2", "3");

    parent.put("sub-parent-1", subparentone);
    parent.put("sub-parent-2", subparenttwo);

   JSONObject finalparent = new JSONObject();
   finalparent.put("parent", parent);

and finalparent JsonObject output as:

{
  "parent": {
    "sub-parent-1": {
      "child-1": 1,
      "child-2": 2
    },
    "sub-parent-2": {
      "child-2": 3
    }
  }
}

Answer 2

I have created class for parent and pass child to it. And convert that parent class into Json using Gson.
