Locale

The set of political, cultural, and region-specific elements represented in an application is called a locale.

Internationalization, also known as "I18n," is the process of separating locale dependencies from an application's source code.
Examples of locale dependencies include messages and user interface labels, character set, encoding, and currency and time formats.

Localization (also called "L10n") is the process of adapting an internationalized application to a specific locale. An application must first be internationalized before it can be localized.

Class java.util.Locale represents a locale in the Java 2 Platform, Standard Edition (J2SE). A Locale object is an identifier in a program that determines such factors as how numbers, currency, and time should be displayed, and the human language used to present data in a user interface.
