Java - 内部化问题

Question

为了使程序国际化，我获得了以下代码，允许我根据用户选择使用多种语言。

import java.util.*; 
public class I18NSample { 
  static public void main(String[] args) { 
    String language, country; 
    if (args.length != 2) { // default is English-language
      language = new String("en"); country = new String("US"); 
    } else { 
      language = new String(args[0]); country = new String(args[1]);
    } 
    Locale currentLocale = new Locale(language, country); 
    ResourceBundle messages = 
      ResourceBundle.getBundle("MessagesBundle", currentLocale);   
    System.out.println(messages.getString("greetings"));
    System.out.println(messages.getString("inquiry")); 
    System.out.println(messages.getString("farewell")); 
  } 
}

这是我的 MessagesBundle 文件:

greetings = Hello.
farewell = Goodbye.
inquiry = How are you?

但是，当在我的程序中实现此代码时，我无法在其他类中使用 messages.getString 函数，并且我在 main 中需要此代码，因为它需要 String[] 参数。有没有办法解决？

当然，只需将消息初始化移至类上方并将其公开，如下所示:

import java.util.*; 
public class I18NSample { 
  public ResourceBundle messages;
  static public void main(String[] args) { 
    String language, country; 
    if (args.length != 2) { // default is English-language
      language = new String("en"); country = new String("US"); 
    } else { 
      language = new String(args[0]); country = new String(args[1]);
    } 
    Locale currentLocale = new Locale(language, country); 
    messages = 
      ResourceBundle.getBundle("MessagesBundle", currentLocale);   
    System.out.println(messages.getString("greetings"));
    System.out.println(messages.getString("inquiry")); 
    System.out.println(messages.getString("farewell")); 
  } 
}

这样，您就可以使用 I18NSample.ResourceBundle 从其他类访问它
