在Java中获取当前周的开始和结束日期 - （MONDAY TO SUNDAY） [英] Get current week start and end date in Java - (MONDAY TO SUNDAY)

问题描述

今天是2014-04-06 - SUNDAY。

Today is 2014-04-06 - SUNDAY.

使用以下代码的输出是： -

开始日期= 2014-04-07

Start Date = 2014-04-07

结束日期= 2014-04-13

End Date = 2014-04-13

我希望输出为： -

开始日期= 2014-03-31

Start Date = 2014-03-31

结束日期= 2014-04-06

End Date = 2014-04-06

// Get calendar set to current date and time
        Calendar c = GregorianCalendar.getInstance();

        System.out.println("Current week = " + Calendar.DAY_OF_WEEK);

        // Set the calendar to monday of the current week
        c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
        System.out.println("Current week = " + Calendar.DAY_OF_WEEK);

        // Print dates of the current week starting on Monday
        DateFormat df = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
        String startDate = "", endDate = "";

        startDate = df.format(c.getTime());
        c.add(Calendar.DATE, 6);
        endDate = df.format(c.getTime());

        System.out.println("Start Date = " + startDate);
        System.out.println("End Date = " + endDate);

推荐答案

我相信只需使用：

c.setFirstDayOfWeek(Calendar.MONDAY);

将解决您的问题...：）

will resolve your issue... :)

说明 ：

EXPLANATION:

在我看来，现在，您的第一天似乎设置在 Calendar.SUNDAY 上。我相信这取决于您的区域设置。

In my opinion, right now, your first day of week seems to be set on Calendar.SUNDAY. I believe that this depends on your Locale.

因此，一个（更好的）替代将初始化您的日历，指定您感兴趣的 Locale ...
例如： c＃GregorianCalendar.getInstance（Locale.US）;

Thus, a (better?) alternative would be to initialise your Calendar specifying the Locale you're interested in... For example:

Calendar c = GregorianCalendar.getInstance(Locale.US);

...将给您您当前的输出，而：

... will give you your current output, while:

Calendar c = GregorianCalendar.getInstance(Locale.FRANCE);

...将给您您的预期输出;）

... will give you your expected output ;)
