DAYS.between

时间:ChronoUnit

e.g.

import java.time.temporal.ChronoUnit;
...

long totalDaysBetween(LocalDate dateBefore, LocalDate dateAfter) {
    return DAYS.between(dateBefore, dateAfter);

如果<>和endDate 是javautil. 日期:

我们可以使用<><><>>><>>>>>>>> 方法,从<><>>>>ChronoUnit< enum:

public long between(Temporal temporal1Inclusive, Temporal temporal2Exclusive) {
    //..
}

www.un.org/Depts/DGACM/index_spanish.htm 纽约总部 <><>>> 填满24小时。

import java.time.temporal.ChronoUnit;

ChronoUnit.DAYS.between(startDate.toInstant(), endDate.toInstant());

//OR 

ChronoUnit.DAYS.between(Instant.ofEpochMilli(startDate.getTime()), Instant.ofEpochMilli(endDate.getTime()));

时间:ChronoUnit。 如下:

Output : *Number of days between the start date : 2015-03-01 and end date : 2016-03-03 is ==> 368. **Number of days between the start date : 2016-03-03 and end date : 2015-03-01 is ==> -368*

public class LocalDateTimeTry {
    public static void main(String[] args) {

        // Date in String format.
        String dateString = "2015-03-01";

        // Converting date to Java8 Local date
        LocalDate startDate = LocalDate.parse(dateString);
        LocalDate endtDate = LocalDate.now();
        // Range = End date - Start date
        Long range = ChronoUnit.DAYS.between(startDate, endtDate);
        System.out.println("Number of days between the start date : " + dateString + " and end date : " + endtDate
                + " is  ==> " + range);

        range = ChronoUnit.DAYS.between(endtDate, startDate);
        System.out.println("Number of days between the start date : " + endtDate + " and end date : " + dateString
                + " is  ==> " + range);

    }

}

每个人都说是使用ChronoUnit.BERS.between,但只有代表你可以称之为 yourself。 因此,你还可以做<条码>第1版。

这两份文件实际上都提到两种做法,并说使用哪一种方法更可读。

圣诞节前几天,从现在起,试图这样做。

System.out.println(ChronoUnit.DAYS.between(LocalDate.now(),LocalDate.of(Year.now().getValue(), Month.DECEMBER, 25)));

各位:

public class DemoDate {
    public static void main(String[] args) {
        LocalDate today = LocalDate.now();
        System.out.println("Current date: " + today);

        //add 1 month to the current date
        LocalDate date2 = today.plus(1, ChronoUnit.MONTHS);
        System.out.println("Next month: " + date2);

        // Put latest date 1st and old date 2nd in  between  method to get -ve date difference
        long daysNegative = ChronoUnit.DAYS.between(date2, today);
        System.out.println("Days : "+daysNegative);

        // Put old date 1st and new date 2nd in  between  method to get +ve date difference
        long datePositive = ChronoUnit.DAYS.between(today, date2);
        System.out.println("Days : "+datePositive);
    }
}

在两个日期之间,休息日。 日期

public static long daysBetweenTwoDates(Date dateFrom, Date dateTo) {
            return DAYS.between(Instant.ofEpochMilli(dateFrom.getTime()), Instant.ofEpochMilli(dateTo.getTime()));
        }

如果目标只是要在几天内实现区别,而且由于上述答复提到了代表方法,希望指出,也可以简单地使用——

public long daysInBetween(java.time.LocalDate startDate, java.time.LocalDate endDate) {
  // Check for null values here

  return endDate.toEpochDay() - startDate.toEpochDay();
}

我知道这个问题涉及 Java8,但 Java9可使用:

public static List<LocalDate> getDatesBetween(LocalDate startDate, LocalDate endDate) {
    return startDate.datesUntil(endDate)
      .collect(Collectors.toList());
}
