Description

The Java ResourceBundle getObject(String key) method gets an object for the given key from this resource bundle or one of its parents. This method first tries to obtain the object from this resource bundle using handleGetObject. If not successful, and the parent resource bundle is not null, it calls the parent's getObject method. If still not successful, it throws a MissingResourceException.

Parameters

key − the key for the desired object

Return Value

This method returns the object for the given key

Exception

• NullPointerException − if key is null

• MissingResourceException − if no object for the given key can be found

Getting a Value as Object for a Key from a Properties File of US Locale

The following example shows the usage of Java ResourceBundle getObject() method to get the object based on key. We've created a resource bundle of US Locale for the corresponding hello_en_US.properties file. Then we retrieved the text assigned to key hello using getObject() and printed it.

package com.tutorialspoint;

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

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

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

      // print the text assigned to key "hello"
      System.out.println(bundle.getObject("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!

Getting a Value as Object for a Key from a Properties File of FRANCE Locale

The following example shows the usage of Java ResourceBundle getObject() method to get the object based on key. We've created a resource bundle of French Locale for the corresponding hello_fr_FR.properties file. Then we retrieved the text assigned to key hello using getObject() and printed it.

package com.tutorialspoint;

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

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

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

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

Output

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

hello = Bonjour le monde!

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

Bonjour le monde!

Getting a Value as Object for a Key from a Properties File of GERMANY Locale

The following example shows the usage of Java ResourceBundle getObject() method to get the object based on key. We've created a resource bundle of German Locale for the corresponding hello_de_DE.properties file. Then we retrieved the text assigned to key hello using getObject() and printed it.

package com.tutorialspoint;

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

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

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

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

Output

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

hello = Hallo Welt!

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

Hallo Welt!
