Question

我有一个要求，我可以提供startDate（27JUL14）和endDate（30JUN15）和dayOfWeek（{{1 }}，4，5）

星期几表示 -

1 - Monday 2 - Tuesday 3 - Wednesday 4 - Thursday 5 - Friday 6 - Saturday 7 - Sunday和startDate之间的持续时间为endDate个月，我需要获得与所提供的6匹配的所有特定日期{ {1}}和dayOfWeek。

StartDate

我试图获得周（星期的开始日期）

EndDate

现在我已尝试创建scheduleDates：

public void calculateScheduleDates(Date periodOfOperationFrom, Date periodOfOperationTo, String dow)
{
       String[] weekDays = dow.replaceAll("\\[", "").replaceAll("\\]", "").split(",");

            int[] dayOfWeek = new int[weekDays.length];

            for (int i = 0; i < weekDays.length; i++) 
            {
               try 
               {
                 dayOfWeek[i] = Integer.parseInt(weekDays[i]);

                 dateTime = (DateTime) DateTime.now().withDayOfWeek(dayOfWeek[i]);

                System.out.println("DateTime :\t"+dateTime);

               } 
               catch (NumberFormatException nfe) {};
            }
}

我需要这个Java解决方案。

我尝试使用public void getWeekDate(String beginDate, String finishDate) { System.out.println("Begindate "+ beginDate + "\t EndDate \t"+finishDate); LocalDate startDate = new LocalDate(2014, 12, 1); LocalDate endDate = new LocalDate(2015, 6, 30); /* These are date format for startDate and endDate which are not working with 27JUL14 format. This also needs to be changed */ LocalDate thisMonday = startDate.withDayOfWeek(DateTimeConstants.MONDAY); if (startDate.isAfter(thisMonday)) { startDate = thisMonday.plusWeeks(1); // start on next monday } else { startDate = thisMonday; // start on this monday } while (startDate.isBefore(endDate)) { dates.add(startDate); startDate = startDate.plusWeeks(1); } System.out.println("Size of List Of Date :\t"+dates+"\n"+dates.size()); }库，但无法获得任何具体结果。

注意：请注意，我需要提到持续时间之间的具体日期，而不仅仅是天数。

请帮助，我非常需要这个。

一种可能性：

解析startDate / endDate
找到startDate行进所需的dayOfWeek
打印该日期，然后添加7天并重复，直到达到endDate。

示例代码：

public class App {

    public static void main(final String[] args) {
        calculateScheduleDates("27JUL14", "30JUN15", DateTimeConstants.MONDAY);
    }

    private static void calculateScheduleDates(final String startDate, final String endDate, final int dayOfWeek) {
        final DateTimeFormatter formatter = DateTimeFormat.forPattern("ddMMMy").withLocale(Locale.US);
        final LocalDate end = LocalDate.parse(endDate, formatter);
        LocalDate start = LocalDate.parse(startDate, formatter);

        // find the first matching date
        while (start.getDayOfWeek() != dayOfWeek) {
            start = start.plusDays(1);
        }

        // compute and print results
        while (start.compareTo(end) < 0) {
            System.out.println(start.toString(formatter).toUpperCase());
            start = start.plusDays(7);
        }
    }
}

输出：

28JUL14
04AUG14
...
15DEC14
22DEC14
...
22JUN15
29JUN15

两个日期之间的周日期和周日期长达6个月
