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

ZonedDateTime.minusMonths介绍

[英]Returns a copy of this ZonedDateTime with the specified period in months subtracted.

This operates on the local time-line, LocalDateTime#minusMonths(long) to the local date-time. This is then converted back to a ZonedDateTime, using the zone ID to obtain the offset.

When converting back to ZonedDateTime, if the local date-time is in an overlap, then the offset will be retained if possible, otherwise the earlier offset will be used. If in a gap, the local date-time will be adjusted forward by the length of the gap.

This instance is immutable and unaffected by this method call.
[中]返回此ZoneDateTime的副本，并减去指定的期间（以月为单位）。
这在本地时间线上运行，本地日期时间#减去本地日期时间的个月（长）。然后将其转换回ZoneDateTime，使用分区ID获取偏移量。
当转换回ZoneDateTime时，如果本地日期时间重叠，那么如果可能，将保留偏移量，否则将使用较早的偏移量。如果存在间隙，本地日期时间将根据间隙的长度向前调整。
此实例是不可变的，不受此方法调用的影响。
