public class Datetestutil {


public static void Main (string[] args) throws Exception {

SimpleDateFormat sdf=new SimpleDateFormat ("YyyyMMdd");
String str= "20110823";
Date dt=sdf.parse (str);
Calendar RightNow = Calendar.getinstance ();
Rightnow.settime (DT);
Rightnow.add (calendar.year,-1);//date minus 1 years
Rightnow.add (calendar.month,3);//date plus 3 months
Rightnow.add (calendar.day_of_year,10);//date plus 10 days
Date Dt1=rightnow.gettime ();
String restr = Sdf.format (DT1);
System.out.println (RESTR);

}

}
