How to add days to a date in Java

I need to get the next date, on click of next link, and get the previous date on click of previous link. How do I increment or decrement dates? I am not getting how to work with date to increment/decrement it.

Answer 1

Calendar cal = Calendar.getInstance();
DateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
Date date = formatter.parse(your_String_date);
cal.setTime(date);

Now do the below as shown:

for increment

cal.add( Calendar.DATE, 1 );

for decrement

cal.add( Calendar.DATE, -1 );

If you want to increment/decrement more days then just replace 1 by your number of days.

Hope it will help you.

Here is the Calendar class of java.
