12-3. Setting the Default Locale
Problem

You want to set the default locale for all locale-sensitive classes.

Solution

Use the Locale.setDefault() method to set a Locale instance that all locale-
sensitive classes will use by default. This method is overloaded with the following two
forms:

• Locale.setDefault(Locale aLocale)
• Locale.setDefault(Locale.Category c, Locale
aLocale)

This example code demonstrates how to set the default locale for all locale-sensit-
ive classes:

Locale.setDefault(Locale.FRANCE);

You can also set the default for two additional locale categories, DISPLAY and
FORMAT :

Locale.setDefault(Locale.Category.DISPLAY, Locale.US);
Locale.setDefault(Locale.Category.FORMAT, Locale.FR);

You can create code that uses these specific locale categories within your applica-
tion to mix locale choices for different purposes. For example, you may choose to use
the DISPLAY locale for ResourceBundle text while using the FORMAT locale for
