How to add or subtract 3 days from currentdate in java?

Question

I need to subtract 3 days from current date and need to store that in Date variable?

[What have you tried](http://mattgemmell.com/2008/12/08/what-have-you-tried/)? Did you take a look at [`Calendar`](http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html) by any chance? — MadProgrammer, Sep 05 '13 at 06:23

Also consider using Joda Time for all your date/time needs - it's much cleaner than `Date`/`Calendar`. — Jon Skeet, Sep 05 '13 at 06:24

You could do this

Calender c = Calender.getInstance();

c.add(DAY_OF_MONTH,3);

c.add(DAY_OF_MONTH,-3);

Date d = c.getTime();

Pull the milliseconds-since-epoch value out, subtract three days of milliseconds from it, shove it into a new Date object.

public static final long ONE_DAY_MILLIS = 86400 * 1000;

Date now = new Date();
Date then = new Date(now.getTime() - (3 * ONE_DAY_MILLIS));
