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

DateTimeFormatter.getZone介绍

[英]Gets the overriding zone to be used during formatting.

This returns the override zone, used to convert instants. By default, a formatter has no override zone, returning null. See #withZone(ZoneId) for more details on overriding.
[中]获取格式化期间要使用的覆盖区域。
这将返回覆盖区域，用于转换实例。默认情况下，格式化程序没有覆盖区域，返回null。有关覆盖的详细信息，请参见#withZone（ZoneId）。

代码示例

private static LocalDate parse(final DateTimeFormatter formatter, final String value) {
 try {
  Instant epoch = Instant.ofEpochMilli(Long.parseLong(value));
  ZonedDateTime zonedDate = epoch.atZone(
    Optional.ofNullable(formatter.getZone())
      .orElse(ZoneId.systemDefault())
    );
  return zonedDate.toLocalDate();
 } catch (NumberFormatException ex) {
  return LocalDate.parse(value, formatter);
 }
}
