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

DateTime.minusYears介绍

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

The calculation will do its best to only change the year field retaining the same month of year. However, in certain circumstances, it may be necessary to alter smaller fields. For example, 2008-02-29 minus one year cannot result in 2007-02-29, so the day of month is adjusted to 2007-02-28.

The following three lines are identical in effect:

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

This datetime instance is immutable and unaffected by this method call.
[中]返回此datetime减去指定年数的副本。
计算将尽最大努力只更改保留一年中同一月份的“年份”字段。但是，在某些情况下，可能需要更改较小的字段。例如，2008-02-29减去一年不能得到2007-02-29，因此将月日调整为2007-02-28。
以下三行实际上是相同的：

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

此datetime实例是不可变的，不受此方法调用的影响。
