Locale类有如下几个构造器：
Locale(String language)
Locale(String language, String country)
Locale(String language, String country, String variant)通过构造方法实例化Locale对象：
public class LocaleTest {
public static void main(String[] args) {
//创建一个通用英语的locale.
Locale locale11 = new Locale("en");
//创建一个加拿大英语的locale.
Locale locale12 = new Locale("en", "CA");
//创建一个美式英语的locale，硅谷的英语
Locale locale13 = new Locale("en", "US", "SiliconValley");
}
}Locale类有一些预定义的Locale对象实例：
| Locale Name | Locale |
|---|---|
| Locale.CHINA | zh_CN |
| Locale.CHINESE | zh |
| Locale.SIMPLIFIED_CHINESE | zh_CN |
| Locale.TRADITIONAL_CHINESE | zh_TW |
| Locale.PRC | zh_CN |
| Locale.TAIWAN | zh_TW |
| Locale.ENGLISH | en |
| Locale.UK | en_GB |
| Locale.US | en_US |
| Locale.FRANCE | fr_FR |
| Locale.FRENCH | fr |
以下例子是德国locale实例以英语、德语和法语提供了信息：
public class LocaleTest {
public static void main(String[] args) {
Locale deLocale = new Locale("de", "DE");
Locale frLocale = new Locale("fr", "FR");
System.out.println("Default language name (default): "
+ deLocale.getDisplayLanguage());
System.out.println("German language name (German): "
+ deLocale.getDisplayLanguage(deLocale));
System.out.println("German language name (French): "
+ deLocale.getDisplayLanguage(frLocale));
}
}输出结果为：
Default language name (default): German
German language name (German): Deutsch
German language name (French): allemand
