//
// code goes over here

}
         


        

Answer 1

This is the method I came up with:

    private Date addLaborDays(Integer days, Date date){
        Collection holidaysList = getHolidays();

        Calendar cal = Calendar.getInstance();
        cal.setTime(date);
        cal.add(Calendar.DATE, 1);
        Date dateTemp = cal.getTime();

        if(days == 1) return dateTemp; 
        if(holidaysList.contains(dateTemp) || DateUtil.isWeekend(dateTemp)){
            return addLaborDays(days, dateTemp);
        } else {
            return addLaborDays(days-1, dateTemp);
        }
    }

Method getHolidays() queries a custom holidays database table, and method DateUtil.isWeekend(dateTemp) returns true if dateTemp is Saturday or Sunday.
