Java 8 减去日期 return 1 天

Java 8 Substracting Dates return 1 day

我正在阅读 Java 8

中的新 java.time API

像这样

public final class DaysWithBaby 
{
   private final LocalDate sheSayYes = LocalDate.of(2008,Month.APRIL,26);
   private final LocalDate today = LocalDate.now().plusDays(1);
   public static void main(String[] args) 
   {
       final DaysWithBaby clazz = new DaysWithBaby();
       System.out.println(Period.between(clazz.sheSayYes,clazz.today).getDays());
       System.out.println(ChronoUnit.DAYS.between(clazz.sheSayYes,clazz.today));  
   }    
}

下面列出了两个输出。

1
2467

我认为这个结果是正确的

System.out.println(ChronoUnit.DAYS.between(clazz.sheSayYes,clazz.today));  

但是这个返回的结果呢1

System.out.println(Period.between(clazz.sheSayYes,clazz.today).getDays());

我做错了什么,非常感谢任何帮助。

Period.getDays、returns 期间的天数部分。

即。 java.time.Period 是以年、月、日衡量的时间量。 Period.getDays returns 这部分的天数。

classPeriod代表若干年月日(按此顺序);如果你只想获得转换它的天数。

private static final LocalDate sheSayYes = LocalDate.of(2008, Month.APRIL,
        26);
private static final LocalDate today = LocalDate.now();

public static void main(String[] args) {
    Period p = Period.between(sheSayYes, today);
    System.out.printf("%d years, %d months, %d days%n", p.getYears(),
            p.getMonths(), p.getDays());
    System.out.println(ChronoUnit.DAYS.between(sheSayYes, today));
}

输出是

6 years, 9 months, 0 days
2466

0 天是正确的,因为今天是 26 号。
