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

Year.from介绍

[英]Obtains an instance of Year from a temporal object.

A TemporalAccessor represents some form of date and time information. This factory converts the arbitrary temporal object to an instance of Year.

The conversion extracts the ChronoField#YEAR field. The extraction is only permitted if the temporal object has an ISO chronology, or can be converted to a LocalDate.

This method matches the signature of the functional interface TemporalQueryallowing it to be used in queries via method reference, Year::from.
[中]从时间对象获取年份的实例。
临时助理代表某种形式的日期和时间信息。该工厂将任意时态对象转换为年份实例。
转换将提取ChronoField#YEAR字段。仅当时态对象具有ISO年表或可以转换为LocalDate时，才允许提取。
此方法匹配函数接口TemporalQueryLow的签名，通过方法引用Year:：from将其用于查询。

代码示例

final Year y = Year.from(ta);
final MonthDay md = MonthDay.from(ta);
final OffsetTime ot = OffsetTime.from(ta);
final Year y = Year.from(ta);
final MonthDay md = MonthDay.from(ta);
final OffsetTime ot = OffsetTime.from(ta);
final Year y = Year.from(ta);
final MonthDay md = MonthDay.from(ta);
return GregorianCalendar.from(y.atMonthDay(md).atStartOfDay(ZoneId.systemDefault()));
