国际化：Java平台下的Locale类

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：

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
