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

Locale.getAvailableLocales介绍

[英]Returns the system's installed locales. This array always includes Locale.US, and usually several others. Most locale-sensitive classes offer their own getAvailableLocales method, which should be preferred over this general purpose method.
[中]返回系统已安装的区域设置。此数组始终包含区域设置。我们，通常还有其他几个人。大多数对区域设置敏感的类都提供了自己的getAvailableCales方法，与此通用方法相比，这应该是首选方法。

/**
 * Initializes the availableLocaleList. It is separate from availableLocaleList() 
 * to avoid the synchronized block affecting normal use, yet synchronized and 
 * lazy loading to avoid a static block affecting other methods in this class. 
 */

  if(cAvailableLocaleList == null) {
    List list = Arrays.asList(Locale.getAvailableLocales());
    cAvailableLocaleList = Collections.unmodifiableList(list);
