LocalDateTime.plus介绍

[英]Returns a copy of this date-time with the specified period added.

This method returns a new date-time based on this date-time with the specified period added. This can be used to add any period that is defined by a unit, for example to add years, months or days. The unit is responsible for the details of the calculation, including the resolution of any edge cases in the calculation.

This instance is immutable and unaffected by this method call.
[中]返回添加了指定期间的此日期时间的副本。
此方法基于此日期时间返回新的日期时间，并添加指定的期间。这可用于添加由单位定义的任何期间，例如添加年、月或日。该单位负责计算的细节，包括计算中任何边缘情况的解决方案。
此实例是不可变的，不受此方法调用的影响。
