如何比较两个Joda时间段 [英] How to compare two Joda time Periods

问题描述

这似乎并不太直接.

我正在尝试:

@Override
public int compare(Period o1, Period o2) {
    return o1.toStandardDays().getDays() > o2.toStandardDays().getDays() ? -1 : (o1.toStandardDays().getDays() == o2.toStandardDays().getDays() ? 0 : 1);
}

但是我得到了这个例外:

But I get this exception:

java.lang.UnsupportedOperationException: Cannot convert to Days as this period contains months and months vary in length
    at org.joda.time.Period.checkYearsAndMonths(Period.java:1455)
    at org.joda.time.Period.toStandardDays(Period.java:1314)

我希望Peroid将具有isLongerThan(Period p)方法.

推荐答案

来自 Joda文档:

要比较两个期间的实际持续时间，请使用toDuration将这两个期间都转换为持续时间，该操作强调根据选择的日期结果可能有所不同.

To compare the actual duration of two periods, convert both to durations using toDuration, an operation that emphasises that the result may differ according to the date you choose.

这两个toDuration方法是

The two toDuration methods are BasePeriod#toDurationTo(ReadableInstant) and BasePeriod#toDurationFrom(ReadableInstant). This means that you must choose either a start or end instant of this period in order to be able to compute its duration.

如果这对您来说是个问题，那么您可能想直接使用

If that is a problem for you, then you might want to directly use Duration instead of Period.
