最佳答案
我有个约会对象:
SimpleDateFormat df = new SimpleDateFormat("yyyy-mm-dd HH:mm");
Date d1 = df.parse(interviewList.get(37).getTime());
value of d1 is Fri Jan 07 17:40:00 PKT 2011
Now I am trying to add 10 minutes to the date above.
Calendar cal = Calendar.getInstance();
cal.setTime(d1);
cal.add(Calendar.MINUTE, 10);
String newTime = df.format(cal.getTime());
值 newTime
更改为 2011-50-07 17:50
but it should be 07-01-2011 17:50
.
它正确地添加分钟,但它也改变了月份,不知道为什么!
