you can use [Calendar](http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html) for date manipulations. — Adi, Sep 02 '14 at 06:26
@Raghuveer Is it so difficult to search for calendar example? There are tons of articles in the web. Please go and search for it. — Seelenvirtuose, Sep 02 '14 at 06:29

If you want add month, or days to your date, use something like that:

public static Date addDays(Date date, int days)
{
    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    cal.add(Calendar.DATE, days); //minus number would decrement the days
    return cal.getTime();
}

to add month use Calendar.Month

Calendar has methods for date manipulations. First create Calendar instance and set date to it

 Calendar calendar = Calendar.getInstance();
 calendar.setTime(new Date());

Then you can use calendar instance to add days like

 calendar.add(Calendar.DATE,10);

to get date from calendar, use

 System.out.println(calendar.getTime());
