Get current date without time

Question

I need to solve following issue. I need to create date for comparison with other, but the date has to be without time due to comparing timemillis.

I have tried many ways, but still unsuccessfully.

I would imagine format like this:

Date(2014-13-03 0:00:00).getTimeMillis();

Do anyone know how?

Solution 1

You could use a Calendar to solve this:

Calendar cal = Calendar.getInstance();
cal.setTime(yourDate);
cal.set(Calendar.HOUR, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
Date desiredDate = cal.getTime();

Solution 2

The best thing is joda-time if you can use it.

Otherwise, use Calendar API. call Calendar.set() to set hour, minute, second and millisecond to zero then you have a Date of the starting of the date.

But, won't new DateTime().withTimeAtStartOfDay() be a much easier expression?

Solution 3

In Java 8 you could do

LocalDate date = LocalDate.of(2014, Month.MARCH, 13);
