        if (bundle != null) {
            String dateString = bundle.getString("date");
            if (dateString != null) {
                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
                Date date = sdf.parse(dateString);
                System.out.println("Date: " + date);
