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

LocalDateTime.withMonth介绍

[英]Returns a copy of this LocalDateTime with the month-of-year altered. The time does not affect the calculation and will be the same in the result. If the day-of-month is invalid for the year, it will be changed to the last valid day of the month.

This instance is immutable and unaffected by this method call.
[中]返回更改月份的此LocalDateTime的副本。时间不影响计算，结果相同。如果月份的日期对该年无效，则该日期将更改为该月的最后一个有效日期。
此实例是不可变的，不受此方法调用的影响。

/**
 * Returns a copy of this {@code ZonedDateTime} with the month-of-year value altered.
 * <p>
 * This operates on the local time-line,
 * {@link LocalDateTime#withMonth(int) changing the month} of the local date-time.
 * This is then converted back to a {@code ZonedDateTime}, using the zone ID
 * to obtain the offset.
 * <p>
 * When converting back to {@code 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.
