我创建了一个程序来计算天数,在我的程序中,我想在当前日期上再添加 7 天。
Which means if today's date is 9/11/2013, i want to make it 9/18/2013 by getting the current date and adding 7 more days to it. How do i implement this.
这意味着如果今天的日期是 2013 年 9 月 11 日,我想通过获取当前日期并再添加 7 天来使其成为 2013 年 9 月 18 日。我如何实现这一点。
I know how to get today's date by using the date class but i don't know to add another 7 days to the current date.
我知道如何使用 date 类获取今天的日期,但我不知道在当前日期上再添加 7 天。

Calendar c = Calendar.getInstance();
c.setTime(new Date()); // Now use today date.
c.add(Calendar.DATE, 15); // Adds 15 days

you can get that by Calendar#add(Calender.DATE,7)
你可以通过 Calendar#add(Calender.DATE,7)
