Year介绍

[英]A year in the ISO-8601 calendar system, such as 2007.

Year is an immutable date-time object that represents a year. Any field that can be derived from a year can be obtained.

Note that years in the ISO chronology only align with years in the Gregorian-Julian system for modern years. Parts of Russia did not switch to the modern Gregorian/ISO rules until 1920. As such, historical years must be treated with caution.

This class does not store or represent a month, day, time or time-zone. For example, the value "2007" can be stored in a Year.

Years represented by this class follow the ISO-8601 standard and use the proleptic numbering system. Year 1 is preceded by year 0, then by year -1.

The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely suitable. However, any application that makes use of historical dates, and requires them to be accurate will find the ISO-8601 approach unsuitable.

Specification for implementors

This class is immutable and thread-safe.
[中]ISO-8601日历系统中的一年，如2007年。
Year是表示年份的不可变日期时间对象。可以从一年中得到任何字段。
请注意，ISO年表中的年份仅与现代格里高利-朱利安体系中的年份一致。直到1920年，俄罗斯部分地区才改用现代的格里高利/ISO规则。因此，必须谨慎对待历史年份。
此类不存储或表示月、日、时间或时区。例如，值“2007”可以存储在一年内。
该类别所代表的年份遵循ISO-8601标准，并使用proleptic编号系统。第一年之前是第0年，然后是第1年。
ISO-8601日历系统是当今世界大部分地区使用的现代民用日历系统。它相当于公历的前身，即今天的闰年规则一直适用。对于今天编写的大多数应用程序，ISO-8601规则完全适用。然而，任何使用历史日期并要求其准确的应用程序都会发现ISO-8601方法不合适。
####实施者规范
这个类是不可变的，是线程安全的。
