Locale class


A Locale class object represents a specific geographical/political/cultural region.

Any operation requiring a Locale to perform its task is called locale-sensitive operation,

and uses the Locale to master information relative to the user.

Locale contains: Language, Script, Country, Variant, Extensions


Display setting


It is possible to independently set the default locale for the display setting that is used in menus and dialogs. Introduced in the Java SE 7 release, the

method takes a Locale.Category parameter. Passing the DISPLAY enum returns the default locale used by the UI.

The corresponding

method allows setting the locale for the desired category.

The no-argument getDefault method returns the DISPLAY default value.

On the Windows platform, these default values are initialized according to the settings in the Windows control panel.
