How to add Date to 1 more day?

[chaohua wang]

Hi, Folks,

I want to add 1 more day for a Date.
I tied to to do like this :

Date completionDate =new Date(completionDate.getTime() +12);

but it doesn't work, 12 hours is not enough?
Please help, thank you very much!

Have a look at the Calendar class. This is the prefered way of manipulating dates in Java. You'll notice there is an add() method that allows you to add time to your date.

With that line of code you are adding 12 milliseconds to the date - not 12 hours.

Also, a day is 24 hours, not 12 hours.

Except in places where daylight saving time applies, sometimes it is 23 or 25 hours. Which is why you should use the Calendar object for date and time arithmetic, as Paul Sturrock said.
