包路径：java.time.LocalTime
类名称：LocalTime
方法名：plusHours

LocalTime.plusHours介绍

[英]Returns a copy of this LocalTime with the specified period in hours added.

This adds the specified number of hours to this time, returning a new time. The calculation wraps around midnight.

This instance is immutable and unaffected by this method call.
[中]返回此LocalTime的副本，并添加指定的时间段（以小时为单位）。
这会将指定的小时数添加到此时间，并返回一个新时间。计算时间大约在午夜。
此实例是不可变的，不受此方法调用的影响。
