How can I increment a date by one day in Java?

Question

I\'m working with a date in this format: yyyy-mm-dd.

How can I increment this date by one day?

Answer 1

Please note that this line adds 24 hours:

d1.getTime() + 1 * 24 * 60 * 60 * 1000

but this line adds one day

cal.add( Calendar.DATE, 1 );

On days with a daylight savings time change (25 or 23 hours) you will get different results!
