AccountToken is an JSON object, not a String...

You'll need to cast it to JSONObject and call get() on it again to get a value from its internal structure

String json = "{\"AccountToken\":{\"string\":\"hello\"},\"Event\":{\"string\":\"t\"}}";
JSONObject genreJsonObject =(JSONObject)JSONValue.parseWithException(json);
JSONObject accountToken = (JSONObject) genreJsonObject.get("AccountToken");
System.out.println(accountToken.get("string"));
==> hello
