It's not always a properties file it might well be also a .class file. Actually the first gets checked whether there are any .class bundle file if none found it tries to find a .properties.

To the point of the other poster, the sentence "A resource bundle file is always a properties file" seems inaccurate. To wit:

From the Java tutorial:

The abstract class ResourceBundle has two subclasses: PropertyResourceBundle and ListResourceBundle.

and a bit down in their page -

A PropertyResourceBundle is backed by a properties file... Each ListResourceBundle is backed by a class file.

So two subclasses of Resource Bundle, each backed by a respective kind of file. Perhaps the wording in the explanation would benefit from a mention that a .class answer is not available, rendering the property file as the only possible choice.

You are right. The explanation has now been fixed.

thank you for your feedback!
