我尝试使用 java.time.Period
,结果与我的手动计算相差三天。
奇怪的是,当我将这段时间分成两个时期时,结果与我的手动计算相符。
第二种方法就像我手动计算时间段的方式。
我是否漏掉了什么?是否有一种标准的日历算法或方法?java.time.Period
使用的算法是什么?
import java.time.LocalDate;
import java.time.Period;
import java.time.temporal.ChronoUnit;
public class test2 {
public static void main(String[] args) {
LocalDate d1 = LocalDate.of(2014, 2, 14);
LocalDate d2 = LocalDate.of(2017, 8, 1);
Period p = Period.between(d1, d2);
//using period between the two dates directly
System.out.println("period between " + d1.toString() + " and " + d2.toString() + " is " + p.getYears()
+ " years " + p.getMonths() + " months " + p.getDays() + " Days");
//dividing the period into two parts
p = Period.between(LocalDate.of(2014, 3, 1), d2);
System.out
.println("period between " + d1.toString() + " and " + d2.toString() + " is " + p.getYears() + " years "
+ p.getMonths() + " months " + d1.until(LocalDate.of(2014, 3, 1), ChronoUnit.DAYS) + " Days");
}
}
