如何在Java中的两个日期之间的除周末，周六或周日之外的每一天获取信息？

Question

大家好，如果在Java中提供了开始日期和结束日期，那么如何生成日期呢？

像下面这样：

例：如果有start date is 15-04-2012并且end date is 15-06-2012我希望日期与以下类似，则列表应省略saturday和sunday

1.15-04-2012, 2.16-04-2012, 3.17-04-2012, . . . . . .
15-06-2012

我已经完成了以下操作，但是如果日期范围是同一个月，它将生成一个月。`

public static ConcurrentHashMap<String, String> getWorkingDaysMap(int year, int month, int day){
        int totalworkingdays=0,noofdays=0;
        String nameofday = "";
        ConcurrentHashMap<String,String> workingDaysMap = new ConcurrentHashMap<String,String>();
        Map<String,String> holyDayMap = new LinkedHashMap<String,String>();
        noofdays = findNoOfDays(year,month,day);

        for (int i = 1; i <= noofdays; i++) {
            Date date = (new GregorianCalendar(year,month - 1, i)).getTime(); // year,month,day
            SimpleDateFormat f = new SimpleDateFormat("EEEE");
            nameofday = f.format(date);

            String daystr="";
            String monthstr="";

            if(i<10)daystr="0";
            if(month<10)monthstr="0";

            String formatedDate = daystr+i+"/"+monthstr+month+"/"+year;

            if(!(nameofday.equals("Saturday") || nameofday.equals("Sunday"))){
                workingDaysMap.put(formatedDate,formatedDate);
                totalworkingdays++;
            }
        }

        return workingDaysMap;
    }

因此，请为我提供建议。

使用以下乔达时间

import org.joda.time.DateTimeConstants;
import org.joda.time.LocalDate;

public class DatesexcludingWeekend {
    public static void main(String[] args) {
        final LocalDate start = new LocalDate(2012, 06, 15);
        final LocalDate end = new LocalDate(2012, 07, 14);
        LocalDate weekday = start;
        if (start.getDayOfWeek() == DateTimeConstants.SATURDAY|| start.getDayOfWeek() == DateTimeConstants.SUNDAY) {
            weekday = weekday.plusWeeks(1).withDayOfWeek(DateTimeConstants.MONDAY);
        }

        while (weekday.isBefore(end)) {
            System.out.println(weekday);
            if (weekday.getDayOfWeek() == DateTimeConstants.FRIDAY)
                weekday = weekday.plusDays(3);
            else
                weekday = weekday.plusDays(1);
        }
    }
