Answer 1

You can convert it to a JavaBean if you want using:

 Gson gson = new GsonBuilder().setPrettyPrinting().create();
 gson.fromJson(jsonString, JavaBean.class)

To use JsonObject, which is more flexible, use the following:

String json = "{\"Success\":true,\"Message\":\"Invalid access token.\"}";
JsonParser jsonParser = new JsonParser();
JsonObject jo = (JsonObject)jsonParser.parse(json);
Assert.assertNotNull(jo);
Assert.assertTrue(jo.get("Success").getAsString());

Which is equivalent to the following:

JsonElement jelem = gson.fromJson(json, JsonElement.class);
JsonObject jobj = jelem.getAsJsonObject();
