LocalDate.add介绍

[英]Return a new LocalDate with the specified (signed) amount of time added to (or subtracted from) the given Calendar field, based on the calendar's rules.

Note that adding any amount to a field smaller than Calendar#DAY_OF_MONTH will remain without effect, as this class does not keep time components.

See Calendar javadocs for more information.
[中]根据日历的规则，返回一个新的LocalDate，在给定的日历字段中添加（或减去）指定的（已签名的）时间量。
请注意，将任何金额添加到小于日历#DAY_OF_MONTH的字段将保持无效，因为此类不保留时间组件。
有关更多信息，请参阅日历javadocs。
