Declaration

Following is the declaration for java.util.ResourceBundle.getBundle() method

public static final ResourceBundle getBundle(String baseName, Locale targetLocale,ResourceBundle.Control control)

Parameters

• baseName − the base name of the resource bundle, a fully qualified class name

• locale − the locale for which a resource bundle is desired

• control − the control which gives information for the resource bundle loading process

Return Value

This method returns a resource bundle for the given base name and a Locale in locales

Exception

• NullPointerException − if baseName, locales or control is null

• MissingResourceException − if no resource bundle for the specified base name in any of the locales can be found.

• IllegalArgumentException − if the given control doesn't perform properly (e.g., control.getCandidateLocales returns null.) Note that validation of control is performed as needed.

Example

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

package com.tutorialspoint;

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

public class ResourceBundleDemo {
   public static void main(String[] args) {

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

      // create a new ResourceBundle with default locale and a Control
      ResourceBundle bundle = ResourceBundle.getBundle("hello", Locale.US, rbc);

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

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!
