ZonedDateTime localization
问题
根据稍后获取的语言环境，我需要输出 ZonedDateTime。有没有办法可以将 ZonedDateTime 的值转换为所需的格式？
ZonedDateTime creationDate = ZonedDateTime.now();
// 根据现有的语言环境转换 creationDate
英文:
I need to output ZonedDateTime according to the locale I get later. Is there any way I can convert the ZonedDateTime value to the required format?
ZonedDateTime creationDate=ZonedDateTime.now();
//convert creationDate depending on the existing locale

ZonedDateTime没有一个固定的格式。ZonedDateTime的概念是无格式的。
格式化器是它们自己的对象（DateTimeFormatter的实例）。它们是可配置的（例如，您可以更改它们的区域设置，它们执行的所有区域设置特定渲染，例如长格式月份名称，将会更改），并且您可以要求它们格式化所提供的ZonedDateTime。
因此，您可以在任何时候创建您的ZonedDateTime对象，将它存储在任何地方。如果在3天后，您需要根据刚刚获取的某个区域设置进行格式化，那么可以这样做：
ZonedDateTime zdt = ZonedDateTime.now();
// 经过了几天
DateTimeFormatter dtf = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.FULL).localizedBy(Locale.FRENCH);
System.out.println(dtf.format(zdt));
英文:
ZonedDateTime doesn't have a format. The concept of a ZonedDateTime is format-less.
Formatters are their own objects (instances of DateTimeFormatter). They are configurable (for example, you can change their locale, and all the locale-specific rendering they do, such as long-form month names, will then change), and you can ask them to format a provided zoneddatetime.
Thus, make your zoneddatetime object whenever you want, store it whereever you want. If, 3 days later, you need to format it according to some locale you just now got, great. Do that then:
ZonedDateTime zdt = ZonedDateTime.now();
// days pass
DateTimeFormatter dtf = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.FULL).localizedBy(Locale.FRENCH);
System.out.println(dtf.format(zdt));
