本文整理了Java中org.threeten.bp.LocalDate类的一些代码示例，展示了LocalDate类的具体用法。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类的具体详情如下：
包路径：org.threeten.bp.LocalDate
类名称：LocalDate
[英]A date without a time-zone in the ISO-8601 calendar system, such as 2007-12-23.
LocalDate is an immutable date-time object that represents a date, often viewed as year-month-day. Other date fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. For example, the value "2nd October 2007" can be stored in a LocalDate.
This class does not store or represent a time or time-zone. Instead, it is a description of the date, as used for birthdays. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.
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.
This class is immutable and thread-safe.
[中]ISO-8601日历系统中没有时区的日期，如2007-12-23。
LocalDate是一个不可变的日期时间对象，它表示一个日期，通常被视为年-月-日。还可以访问其他日期字段，例如年中的日期、周中的日期和年中的周。例如，值“2007年10月2日”可以存储在LocalDate中。
此类不存储或表示时间或时区。相反，它是对日期的描述，用于生日。如果没有诸如偏移量或时区之类的附加信息，它不能表示时间线上的某个瞬间。
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，即今天的闰年规则在任何时候都适用。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，并且是线程安全的。
