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？

嗨，如果在java中提供开始日期和结束日期，如何生成日期？

如下：

例如：如果start date is 15-04-2012 ， end date is 15-06-2012 ，我希望日期如下，列表应该省略saturday和sunday

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

我已经完成了以下操作，但如果日期范围是同一个月，它将生成一个月。 `

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

所以请建议我如何去做。

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); } } 

Answer 3

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); } }
