        cal.set(Calendar.YEAR, year);
        cal.set(Calendar.WEEK_OF_YEAR, weekId);
        cal.set(Calendar.DAY_OF_WEEK, weekDay);

        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
        return  sdf.format(cal.getTime());    
        public static void main(String args[]){
        GetDateFromDay dt = new GetDateFromDay();
