线程＆＃34; main＆＃34;中的例外情况java.util.MissingResourceException：无法找到基本名称Internationalization / StatsBundle，locale en_US的包

Question

我目前在Java教程Oracle上学习国际化。当我尝试运行下面的代码时，IDE始终显示错误消息：

Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name Internationalisation/StatsBundle, locale en_US
    at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1564)
    at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1387)
    at java.util.ResourceBundle.getBundle(ResourceBundle.java:845)
    at Internationalisation.ListDemo.displayValues(ListDemo.java:20)
    at Internationalisation.ListDemo.main(ListDemo.java:41)
Java Result: 1

这是我的代码：

public class ListDemo {

   static void displayValues(Locale currentLocale) {

      ResourceBundle stats = 
         ResourceBundle.getBundle("Internationalisation/StatsBundle",currentLocale);

      Integer gdp = (Integer)stats.getObject("GDP");
      System.out.println("GDP = " + gdp.toString());
      Integer pop = (Integer)stats.getObject("Population");
      System.out.println("Population = " + pop.toString());
      Double lit = (Double)stats.getObject("Literacy");
      System.out.println("Literacy = " + lit.toString());

   } // displayValues

   static public void main(String[] args) {

      Locale[] supportedLocales = {
         new Locale("en", "US"),
         new Locale("ja","JP"),
         new Locale("fr","FR")
      };

      for (int i = 0; i < supportedLocales.length; i ++) {
         System.out.println("Locale = " + supportedLocales[i]);
         displayValues(supportedLocales[i]);
         System.out.println();
      }

   } // main

} // class
