Check if date is within time range using Joda or s

问题:

I have first time as string '12:00:00' and another '19:00:00'. How to check time portion of the day is within these time values?

回答1:

Using Joda Time you could do something like this:

DateTime start = new DateTime(2010, 5, 25, 12, 0, 0, 0);
DateTime end = new DateTime(2010, 5, 25, 21, 0, 0, 0);
Interval interval = new Interval(start, end);
DateTime test = new DateTime(2010, 5, 25, 16, 0, 0, 0);
System.out.println(interval.contains(test));

Create calendar instances of the start and end times for the same day as your 'test' date. Then you can easily compare the calendar objects to determine if the current date is inside or outside the range.
