java提供了一个资源类java.util.ResourceBundle来试下多国语言版本。其实ResourceBundle只是一个抽象的类，她有两个子类：ListResourceBundle,和,PropertyResourceBundle.前一个子类需要编写不同的国家语言信息放置在对象类中，下面将实例演示，后一个子类是需要编写不同国家语言的文件后缀为.properties（）来存放语言信息，这部分内容读者可以在国际化标签以及Struts时了解到。例如，存放在RES_zh_EN.propertieh和存放英文的RES_en_US.properties资源文件.
1 package cn.com.resouce; 2 import java.util.ListResourceBundle; 3 4 public class RES_zh_CN extends ListResourceBundle { 5 6 static final Object[][] contents = new String[][]{ 7 {"version","这是中文版"}, 8 {"title","中文版本"}, 9 {"index","首页"}, 10 {"news","新闻"}, 11 {"life","生活"}, 12 {"sports","体育"}, 13 {"entertainment","娱乐"} 14 }; 15 16 17 @Override 18 protected Object[][] getContents() { 19 // TODO Auto-generated method stub 20 return contents; 21 } 22 23 }
1 package cn.com.resouce; 2 import java.util.ListResourceBundle; 3 4 public class RES_en_US extends ListResourceBundle { 5 6 //创建对应的中文文本信息 7 8 static final Object[][] contents = new String[][]{ 9 10 {"version","this is english"}, 11 {"title","english"}, 12 {"index","index"}, 13 {"news","news"}, 14 {"life","life"}, 15 {"sports","sports"}, 16 {"entertainment","entertainment"} 17 }; 18 19 20 @Override 21 protected Object[][] getContents() { 22 // TODO Auto-generated method stub 23 return contents; 24 } 25 26 }
