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

ZoneId.ofOffset介绍

[英]Obtains an instance of ZoneId wrapping an offset.

If the prefix is "GMT", "UTC", or "UT" a ZoneIdwith the prefix and the non-zero offset is returned. If the prefix is empty "" the ZoneOffset is returned.
[中]获取包裹偏移的ZoneId实例。
如果前缀为“GMT”、“UTC”或“UT”，则返回带有前缀和非零偏移的区域ID。如果前缀为空“”，则返回ZoneOffset。
