Setting Parent Bundle in a Resource Bundle of US Locale Example

The following example shows the usage of Java ResourceBundle setParent() method. In this example, we've extended ResourceBundle Class and implemented setParent() method and setting the super parent.

package com.tutorialspoint;

import java.util.Enumeration;
import java.util.Locale;
import java.util.ResourceBundle;
import java.util.StringTokenizer;

public class ResourceBundleDemo extends ResourceBundle {

   @Override
   public Object handleGetObject(String key) {
      if (key.equals("hello")) {
         return "Hello World!";
      } else {
         return null;
      }
   }

   @Override
   public Enumeration getKeys() {
      StringTokenizer key = new StringTokenizer("Hello World!");
      return key;
   }

   @Override
   protected void setParent(ResourceBundle parent) {
      super.setParent(parent);
   }

   public static void main(String[] args) {

      // create a new ResourceBundle with specified locale
      ResourceBundle bundle = ResourceBundle.getBundle("hello", Locale.US);

      // print the string array assigned to key "hello"
      System.out.println("" + bundle.getString("hello"));
   }
}

Output

Assuming we have a resource file hello_en_US.properties available in your CLASSPATH, with the following content. This file will be used as an input for our example program −

hello = Hello World!

Let us compile and run the above program, this will produce the following result −

Hello World!

      System.out.println("" + bundle.getString("hello"));
   }
}

Output

hello = Bonjour le monde!

Let us compile and run the above program, this will produce the following result −
