Java 8 Substracting Dates返回1天

Question

我正在阅读Java 8中的新的java.time API

像这样的东西

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));  
   }    
}

两个输出都列在下面.

1
2467

我认为这个结果是正确的

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

但是这个结果又回来了 1

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

我做错了什么任何帮助都非常感激.

Answer 1

该课程Period代表若干年,月和日(按此顺序); 如果你想获得转换它的日子.

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,因为今天是第26天.
