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

LocalDateTime.minusDays介绍

[英]Returns a copy of this LocalDateTime with the specified period in days subtracted.

This method subtracts the specified amount from the days field incrementing the month and year fields as necessary to ensure the result remains valid. The result is only invalid if the maximum/minimum year is exceeded.

For example, 2009-01-01 minus one day would result in 2008-12-31.

This instance is immutable and unaffected by this method call.
[中]返回此LocalDateTime的副本，并减去指定的期间（以天为单位）。
此方法从天数字段中减去指定的金额，根据需要增加月份和年份字段，以确保结果仍然有效。仅当超过最大/最小年份时，结果才无效。
例如，2009-01-01减去一天将导致2008-12-31。
此实例是不可变的，不受此方法调用的影响。
