Question

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？

如下：

例如：如果{i}}和start date is 15-04-2012有这个我想要的日期如下，则列表应省略end date is 15-06-2012和saturday

sunday 1.15-04-2012, 2.16-04-2012, 3.17-04-2012, . . . . . .

我已经完成了以下操作，但如果日期范围是同月，它将生成一个月。 `

15-06-2012

所以请建议我如何去做。

此致贝

Answer 1

int noOfDaysBetween = 5;
Calendar cal  = Calendar.getInstance();
cal.setTime(startDate);

for(int index = 0 ; index < noOfDaysBetween; index++){
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
    if( dayOfWeek!=Calendar.SUNDAY && dayOfWeek!=Calendar.SATURDAY) {
        System.out.println(cal.getTime());
    }
    cal.add(Calendar.DATE, 1);
}

Answer 2

public static void main(String[] args) {

    Calendar calendar = Calendar.getInstance();

    //15-04-2012
    calendar.set(Calendar.DAY_OF_MONTH, 15);
    calendar.set(Calendar.YEAR, 2012);
    calendar.set(Calendar.HOUR, 0);
    calendar.set(Calendar.MINUTE, 0);
    calendar.set(Calendar.SECOND, 0);
    calendar.set(Calendar.MONTH, 3);
    Date start = calendar.getTime();

    //15-06-2012
    calendar.set(Calendar.MONTH, 5);
    Date end = calendar.getTime();

    calendar.setTime(start);
    Date d = null;
    while((d = calendar.getTime()).before(end) || d.equals(end)) {
        int day = calendar.get(Calendar.DAY_OF_WEEK);
        if (day != Calendar.SATURDAY && day != Calendar.SUNDAY) {
            System.out.println(d);
        }
        calendar.add(Calendar.DAY_OF_MONTH, 1);
    } 
}

我更喜欢使用LocalDate。

import java.time.DayOfWeek;
import java.time.LocalDate;

public class Game {
    public static void main(String[] args) {
       LocalDate start = LocalDate.of(2018, 6, 1);
       LocalDate end = LocalDate.of(2018, 8, 1);

       LocalDate d = start;
       while(d.compareTo(end) <= 0) {
         if (d.getDayOfWeek() != DayOfWeek.SATURDAY && d.getDayOfWeek() != DayOfWeek.SUNDAY) {
            System.out.println(d);
         }
         d = d.plusDays(1);
      }
   }
}

使用以下joda-time

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);
        }
    }

如何获得除了周末，周六或周日之间的每一天在两个日期之间的Java？
