Expires Today in Java

I need to check if the set date after today was 23:59:59, how can I create a date object that is 23:59:59 today?

Use java.util.Calendar :

Calendar cal = Calendar.getInstance(); // represents right now, i.e. today date
cal.set(Calendar.HOUR_OF_DAY, 23);
cal.set(Calendar.MINUTE, 59);
cal.set(Calendar.SECOND, 59);
cal.set(Calendar.MILLISECOND, 999); // credit to f1sh

Date date = cal.getTime();

I think you might be approaching this from a slightly wrong angle. Instead of trying to create an instance of Date that is one atom before midnight, a better approach would be to create a date representing midnight and check if the current time is strictly less. I believe this will be a little clearer in terms of your intentions for someone else to read the code too.

( ). Joda.

long timeStampOfTomorrow = new Date().getTime() + 86400000L;
Date dateToCheck = new Date(timeStampOfTomorrow);


Calendar today = Calendar.getInstance();
today.set(Calendar.HOUR_OF_DAY, 23);
today.set(Calendar.MINUTE, 59);
today.set(Calendar.SECOND, 59);
today.set(Calendar.MILLISECOND, 999);

boolean isExpired = dateToCheck.after(today.getTime());

Joda . - .

public boolean isRentalOverdue(DateTime datetimeRented) {
    Period rentalPeriod = new Period().withDays(2).withHours(12);
    return datetimeRented.plus(rentalPeriod).isBeforeNow();
}

Date.before(Date) Date.after(Date)

Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, 23);
c.set(Calendar.SECOND, 59);
c.set(Calendar.MINUTE, 59);

Date d = c.getTime()

Date x = // other date from somewhere

x.after(d);
