Java Date & Time of Day
提问by Gaz
I have an application that passes in java.util.Date. I want to check whether this date is within a specified time of day (e.g. between 10:30 & 11:30), I don't care about the date, just the time of day.
我有一个传入 java.util.Date 的应用程序。我想检查这个日期是否在一天中的指定时间（例如 10:30 和 11:30 之间），我不关心日期，只关心一天中的时间。
Can anyone show me a simple way to do this?
谁能告诉我一个简单的方法来做到这一点？
Thanks
谢谢

This is what the Calendarclass is for. Assuming dateis your Dateobject:
这就是Calendar班级的用途。假设date是你的Date对象：
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int hour = cal.get(Calendar.HOUR_OF_DAY);
int minutes = cal.get(Calendar.MINUTE);
if (hour == 10 && minutes >= 30 || hour == 11 && minutes <= 30) {
...
}
