In my database i have a field StartDate and EndDate Now entering date from my jsp and fetching it in the servlet
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Date date = new Date(request.getParameter("date"));
SimpleDateFormat simpleDateformat=new SimpleDateFormat("yyyy");
System.out.println("Year: " + simpleDateformat.format(date));
String k= simpleDateformat.format(date);
}
But I have to add 4 with the year value and generate the date after 4 years of Starting Date and store it into the database

The given code is useful.
try{
DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
Date d=(Date)formatter.parse("30-03-2012");
Calendar cal=Calendar.getInstance();
cal.setTime(d);
cal.add(Calendar.YEAR, 4);
String newdate = formatter.format(cal.getTime());
System.out.println(newdate);
}
catch(Exception e){}
