Example

The following example shows the usage of java.util.ResourceBundle.Control.getCandidateLocales() method.

package com.tutorialspoint;

import java.util.Locale;
import java.util.ResourceBundle;
import java.util.ResourceBundle.Control;

public class ResourceBundleControlDemo {

   public static void main(String[] args) {

      // create a new ResourceBundle.Control with default format
      ResourceBundle.Control rbc =
              ResourceBundle.Control.getControl(Control.FORMAT_DEFAULT);

      // print the CandidateLocales
      System.out.println("" + rbc.getCandidateLocales("hello", Locale.US));

   }
}

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:

[en_US, en, ]
