    Calendar cal  = Calendar.getInstance();                                               int  day = cal.get(cal.DAY_OF_WEEK);

    Calendar cal1 = Calendar.getInstance();
    Calendar cal2 = Calendar.getInstance();
    cal1.setTime(date1);
    cal2.setTime(date2);

    int numberOfDays = 0;

        {
            numberOfDays++;
          session.setAttribute("numberOfDays",numberOfDays);
            cal1.add(Calendar.DATE,1);
        }else {
            cal1.add(Calendar.DATE,1);
        }

    }

您需要与 Calendar.DAY_OF_WEEK 而不是 Calendar.DAY_OF_MONTH 进行比较

所以你的条件变成了:

if ((Calendar.SATURDAY != cal1.get(Calendar.DAY_OF_WEEK))
                    && (Calendar.SUNDAY != cal1.get(Calendar.DAY_OF_WEEK))) {
