You might want to look at what GregorianCalendar can do for you. The basic constrictor creates a GregorianCalendar object to today and the roll method can increment the date a specific amount af time. The only draw back is formatting the date that it creates into something usable. But, with the help of the get method GregorianCalendar provides and DecimalFormat you should be on your way.

I Hope This Helps

There is a "bulldog" method. Take n, multiply by 86400000 (# of milliseconds in a day). Add to the long rep of the date, make new date with new value. You have now added n days to the date.
I agree. Here's the link: http://aspose.com/file-tools
