一、Locale类

通过设定Locale可以为特定的国家或地区提供符合当地文化习惯的字体、符号和图标等

一个Locale实例代表一种特定的语言和地区

通过Locale对象输出对应语言和地区的时间、数字等格式

import java.util.Locale;
 
public class MainClass_Locale_1 {
    public static void main(String[] args){
        Locale locale1 = new Locale("en","US");
        System.out.println("语言编码："+locale1.getLanguage());
        System.out.println("语言名称："+locale1.getDisplayLanguage());
        System.out.println("国家编码："+locale1.getCountry());
        System.out.println("国家名称："+locale1.getDisplayCountry());
 
        Locale locale2 = Locale.getDefault();
        System.out.println("语言编码："+locale2.getLanguage());
        System.out.println("语言名称："+locale2.getDisplayLanguage());
        System.out.println("国家编码："+locale2.getCountry());
        System.out.println("国家名称："+locale2.getDisplayCountry());
    }
}

二、ResourceBundle类

ResourceBundle类用于加载国家和语言的资源包

资源文件命名方式：

• baseName_language_country.properties
• baseName_language.properties
• baseName.properties
• baseName：资源文件的名称
• language/country ：java支持的语言/国家

• 新建3个资源文件

• 写入相关内容

import java.util.Locale;
import java.util.ResourceBundle;
 
public class TestResourceBundle {
    public static void main(String[] args) {
        //  1.读取默认资源文件，跟Locale默认值有关
        ResourceBundle resourceBundle1 = ResourceBundle.getBundle("myProperties",
                Locale.getDefault());
        System.out.println(resourceBundle1.getBaseBundleName());
        System.out.println(resourceBundle1.getString("name"));
        System.out.println("-------------------------------------");
 
        //  2.英语资源文件
        Locale locale2 = new Locale("en","US");
        ResourceBundle resourceBundle2 = ResourceBundle.getBundle("myProperties_en_US", locale2);
        System.out.println(resourceBundle2.getBaseBundleName());
        System.out.println(resourceBundle2.getString("name"));
        System.out.println("-------------------------------------");
 
        //  3.中文资源文件
        Locale locale3 = new Locale("zh","CN");
        ResourceBundle resourceBundle3 = ResourceBundle.getBundle("myProperties_zh_CN", locale3);
        System.out.println(resourceBundle3.getBaseBundleName());
        System.out.println(resourceBundle3.getString("name"));
        System.out.println("-------------------------------------");
    }
}
