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

LocalDate.minusYears介绍

[英]Returns a copy of this date minus the specified number of years.

This subtracts the specified number of years from the date. If subtracting years makes the day-of-month invalid, it is adjusted to the last valid day in the month. This LocalDate instance is immutable and unaffected by this method call.

The following three lines are identical in effect:

LocalDate subtracted = dt.minusYears(6); 
LocalDate subtracted = dt.minus(Period.years(6)); 
LocalDate subtracted = dt.withFieldAdded(DurationFieldType.years(), -6);

[中]返回此日期减去指定年数的副本。
这将从日期中减去指定的年数。如果减去年份使月日无效，则调整为该月的最后一个有效日。此LocalDate实例是不可变的，不受此方法调用的影响。
以下三行实际上是相同的：

LocalDate subtracted = dt.minusYears(6); 
LocalDate subtracted = dt.minus(Period.years(6)); 
LocalDate subtracted = dt.withFieldAdded(DurationFieldType.years(), -6);
