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

DateTimeFormatter.withLocale介绍

[英]Returns a new formatter with a different locale that will be used for printing and parsing.

A DateTimeFormatter is immutable, so a new instance is returned, and the original is unaltered and still usable.
[中]返回将用于打印和分析的具有不同区域设置的新格式化程序。
DateTimeFormatter是不可变的，因此会返回一个新实例，而原始实例是不变的，并且仍然可用。
