allows user customization; a user whose language is not provided for,
or who wishes to change the wording somewhat due to local variations

as any of your Java classes. The reason is that the
ResourceBundle constructs a class dynamically,
with the same name as the resource files. You can confirm this by
running java -verbose on any of the programs
that use the I18N class from this chapter.
Here is a sample for a simple
browser (see the
MenuIntl program in Section 14.12):
# Default Menu properties # The File Menu file.label=File Menu file.new.label=New File file.new.key=N
Creating the default properties file will usually not be a problem, but creating properties files for other languages might.

If you are shipping commercial software, you need to identify your target markets and understand which ...
