java - 试图获取本周星期一的日期

Question

我已经实现了一种方法来获取本周星期一的日期，并且我已将星期一指定为一周的第一天。

但是，无论我做什么，它都会返回 Sun Mar 24 15:03:07 GMT 2013。我看不出这里有什么问题。有人能帮忙吗？

public static Date getFirstDayOfWeekDate()
{
    Calendar cal = Calendar.getInstance();
    cal.setFirstDayOfWeek(2);
    cal.set(Calendar.DAY_OF_WEEK,
    cal.getActualMinimum(Calendar.DAY_OF_WEEK));
    Date firstDayOfTheWeek = cal.getTime();
    return firstDayOfTheWeek;
}

试试这个：

public static Date getFirstDayOfWeekDate() {
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.DAY_OF_WEEK,
            cal.getActualMinimum(Calendar.DAY_OF_WEEK));
    Date now = new Date();
    cal.setTime(now);
    int week = cal.get(Calendar.DAY_OF_WEEK);
    return new Date(now.getTime() - 24 * 60 * 60 * 1000 * (week - 1));
}

这个对我有用：

    Calendar c = Calendar.getInstance();
    c.setFirstDayOfWeek(Calendar.MONDAY);
    c.setTime(new Date());
    int today = c.get(Calendar.DAY_OF_WEEK);
    c.add(Calendar.DAY_OF_WEEK, -today+Calendar.MONDAY);
    System.out.println("Date "+c.getTime());

只需在星期几中添加一个：

Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_WEEK, cal.getActualMinimum(Calendar.DAY_OF_WEEK) + 1);
return cal.getTime();

或使用JodaTime

LocalDate.now().withDayOfWeek(DateTimeConstants.MONDAY);

来自Joda 时间：一周的第一天？
