Period.plusDays介绍

[英]Returns a copy of this period with the specified days added.

This adds the amount to the days unit in a copy of this period. The years and months units are unaffected. For example, "1 year, 6 months and 3 days" plus 2 days returns "1 year, 6 months and 5 days".

This instance is immutable and unaffected by this method call.
[中]返回添加了指定天数的此时段的副本。
这会将金额添加到此期间副本中的天数单位。年和月单位不受影响。例如，“1年、6个月和3天”加上2天返回“1年、6个月和5天”。
此实例是不可变的，不受此方法调用的影响。
