Java获取上周的日期列表

Question

我在尝试根据指定日期获取上周的日期列表时遇到了一些问题。这是我的代码：        SimpleDateFormat formatter = new SimpleDateFormat("EEE MMM dd");        Date refDate = null;        try {            refDate = formatter.parse("Sun Aug 05");        } catch (ParseException e) {            e.printStackTrace();        }        Date[] days = reservationViewModel.getDaysOfWeek(refDate, Calendar.getInstance().getFirstDayOfWeek());        for (Date day : days) {            // display                    }以及获取日期列表的代码：public static Date[] getDaysOfWeek(Date refDate, int firstDayOfWeek) {    Calendar calendar = Calendar.getInstance();    calendar.setTime(refDate);    calendar.set(Calendar.DAY_OF_WEEK, firstDayOfWeek);    Date[] daysOfWeek = new Date[7];    for (int i = 0; i < 7; i++) {        daysOfWeek[i] = calendar.getTime();        calendar.add(Calendar.DAY_OF_MONTH, 1);    }    return daysOfWeek;}但是，我得到的结果是：Sun Aug 02Mon Aug 03Tue Aug 04Wed Aug 05Thu Aug 06Fri Aug 07Sat Aug 08日期都错了。应该是从7月29日到8月4日。有任何想法吗？谢谢！
