本文整理了Java中java.time.temporal.TemporalQueries.zone()方法的一些代码示例，展示了TemporalQueries.zone()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TemporalQueries.zone()方法的具体详情如下：
包路径：java.time.temporal.TemporalQueries
类名称：TemporalQueries
方法名：zone

TemporalQueries.zone介绍

[英]A lenient query for the ZoneId, falling back to the ZoneOffset.

This queries a TemporalAccessor for the zone. It first tries to obtain the zone, using #zoneId(). If that is not found it tries to obtain the #offset().

In most cases, applications should use this query rather than #zoneId().

This query examines the ChronoField#OFFSET_SECONDSfield and uses it to create a ZoneOffset.

The method ZoneId#from(TemporalAccessor) can be used as a TemporalQuery via a method reference, ZoneId::from. That method is equivalent to this query, except that it throws an exception if a zone cannot be obtained.
[中]对ZoneId的宽松查询，回到ZoneOffset。
这将查询区域的临时助理。它首先尝试使用#zoneId（）获取区域。如果没有找到，它会尝试获取#offset（）。
在大多数情况下，应用程序应该使用此查询，而不是#zoneId（）。
此查询检查ChronoField#OFFSET_SECONDSfield，并使用它创建区域偏移。
方法ZoneId#from（TemporalAccessor）可以通过方法引用ZoneId:：from用作临时查询。该方法与此查询等效，只是如果无法获取区域，它会引发异常。
