Date Calculations - Adding 1 to the day and adjusting month/year

Question

Hi all,
I have a date field in MM/ DD/ YYYY format. If I add 1 to the DD (day) field, and I hit the end
of the month/year I need to adjust the MM and YYYY accordingly.
Is there is an existing class/method in the JAVA API that would handle somthing like this??
If so , I can't find it..... I don't want to re-invent the wheel creating a Date Handling routine just
for this program.......
Thanks very much

This is overkill... (and sorry that this post is over a year later than the original post... hopefully somebody will benefit from it :)
Calendar.getInstance() by default instanciates a GregorianCalendar
object. (check the src).
Therefore:
Calendar cal = Calendar.getInstance();
cal.setTime(d); // where d = java.util.Date or java.sql.Timestamp
cal.add(Calendar.DATE, numberOfDays);
return cal.getTime();
public static java.util.Date
adjustDateBy(java.util.Date d, int numberOfDays) {
java.util.GregorianCalendar cal = new
java.util.GregorianCalendar();
     cal.setTime(d);
cal.add(java.util.GregorianCalendar.DATE,
numberOfDays);
     return cal.getTime();
