Most of the answer I've found online didn't work as expected, so I tweaked an example on this thread, How to get current date and add five working days in Java. The code below appears to work better.

public static Date addWorkingDays(Date date, int days) {
    if (days > 0) {
        Calendar cal = Calendar.getInstance();
        cal.setTime(date);

        int daysAdded = 0;
        do {
            cal.add(Calendar.DATE, 1);
            if (isWorkingDay(cal)) {
                daysAdded++;
            }
        } while (daysAdded < days);

        return cal.getTime();;
    } else {
        return date;
    }
}


 private static boolean isWorkingDay(Calendar cal) {
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
    if (dayOfWeek == Calendar.SUNDAY || dayOfWeek == Calendar.SATURDAY)
        return false;
    // tests for other holidays here        
    return true;
 }
