计算Java中两个日期之间的工作日数 [英] Calculate number of weekdays between two dates in Java

问题描述

任何人都可以向我指出一些Java代码片段，其中我可以在两个日期之间获得业务（星期六和星期日除外）。

Can anyone point me to some Java snippet wherein i can get business (except Sat and Sun) days between two dates.

推荐答案

public static int getWorkingDaysBetweenTwoDates(Date startDate, Date endDate) {
    Calendar startCal = Calendar.getInstance();
    startCal.setTime(startDate);        

    Calendar endCal = Calendar.getInstance();
    endCal.setTime(endDate);

    int workDays = 0;

    //Return 0 if start and end are the same
    if (startCal.getTimeInMillis() == endCal.getTimeInMillis()) {
        return 0;
    }

    if (startCal.getTimeInMillis() > endCal.getTimeInMillis()) {
        startCal.setTime(endDate);
        endCal.setTime(startDate);
    }

    do {
       //excluding start date
        startCal.add(Calendar.DAY_OF_MONTH, 1);
        if (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY && startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) {
            ++workDays;
        }
    } while (startCal.getTimeInMillis() < endCal.getTimeInMillis()); //excluding end date

    return workDays;
}

开始日期和结束日期是独家的，仅限给定
日期之间的天数将被计算在内。不包括开始日期和结束日期。

Start date and end date are exclusive, Only the days between given dates will be counted. Start date and end date will not be included.
