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

LocalDateTime.withDayOfMonth介绍

[英]Returns a copy of this LocalDateTime with the day-of-month altered. If the resulting LocalDateTime is invalid, an exception is thrown. The time does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.
[中]返回更改了月份日期的LocalDateTime的副本。如果生成的LocalDateTime无效，将引发异常。时间不影响计算，结果相同。
此实例是不可变的，不受此方法调用的影响。
