How can you implement internationalization in a J2EE application using Resource Bundle in Java?

To implement internationalization in a J2EE application using Resource Bundle in Java, you can follow these steps:

1. Create resource properties files for each language you want to support. For example, create messages_en.properties for English and messages_fr.properties for French.
2. Store key-value pairs in each properties file, where the keys represent the message keys and the values represent the translated messages.
3. In your Java code, load the appropriate resource bundle based on the user's preferred language setting. This can be done using the ResourceBundle class provided by Java.
4. Retrieve the localized messages using the keys from the resource bundle in your application for displaying to the user.

By following this approach, you can easily support multiple languages in your J2EE application by simply creating and maintaining resource bundles for each supported language, making your application more accessible to a global audience.
