本文整理了Java中java.time.ZonedDateTime.getZone()方法的一些代码示例，展示了ZonedDateTime.getZone()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。ZonedDateTime.getZone()方法的具体详情如下：
包路径：java.time.ZonedDateTime
类名称：ZonedDateTime
方法名：getZone

ZonedDateTime.getZone介绍

[英]Gets the time-zone, such as 'Europe/Paris'.

This returns the zone ID. This identifies the time-zone ZoneRulesthat determine when and how the offset from UTC/Greenwich changes.

The zone ID may be same as the #getOffset(). If this is true, then any future calculations, such as addition or subtraction, have no complex edge cases due to time-zone rules. See also #withFixedOffsetZone().
[中]获取时区，例如“欧洲/巴黎”。
这将返回区域ID。它标识时区区域，确定UTC/格林威治的偏移量何时以及如何变化。
区域ID可能与#getOffset（）相同。如果这是真的，那么任何未来的计算，例如加法或减法，都不会因为时区规则而出现复杂的边缘情况。另请参见#withFixedOffsetZone（）。
