Answer 1

Something like this:
    SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy");
    Date date = sdf.parse("04-JAN-2009");
    Calendar calendar = new GregorianCalendar();
    calendar.setTime(date);
    calendar.add(Calendar.DAY_OF_MONTH, 7);
    System.out.println(sdf.format(calendar.getTime()));
    // OUTPUT:
    // 11-Jan-2009
