Classes which can be * passed a Locale object tailor their information for a given locale. For * instance, currency number formatting is handled differently for the USA * and France. * *

Locales are made up of a language code, a country code, and an optional * set of variant strings. Language codes are represented by * * ISO 639:1988 w/ additions from ISO 639/RA Newsletter No. 1/1989 * and a decision of the Advisory Committee of ISO/TC39 on August 8, 1997. * *

Country codes are represented by * * ISO 3166. Variant strings are vendor and browser specific. Standard * variant strings include "POSIX" for POSIX, "WIN" for MS-Windows, and * "MAC" for Macintosh. When there is more than one variant string, they must * be separated by an underscore (U+005F). * *

The default locale is determined by the values of the system properties * user.language, user.region, and user.variant, defaulting to "en". Note that * the locale does NOT contain the conversion and formatting capabilities (for * that, use ResourceBundle and java.text). Rather, it is an immutable tag * object for identifying a given locale, which is referenced by these other * classes when they must make locale-dependent decisions. * * @see ResourceBundle * @see java.text.Format * @see java.text.NumberFormat * @see java.text.Collator * @author Jochen Hoenicke * @author Paul Fisher * @author Eric Blake * @since 1.1 * @status updated to 1.4 */ public final class Locale implements Serializable, Cloneable { /** Locale which represents the English language. */ public static final Locale ENGLISH = new Locale("en"); /** Locale which represents the French language. */ public static final Locale FRENCH = new Locale("fr"); /** Locale which represents the German language. */ public static final Locale GERMAN = new Locale("de"); /** Locale which represents the Italian language. */ public static final Locale ITALIAN = new Locale("it"); /** Locale which represents the Japanese language. */ public static final Locale JAPANESE = new Locale("ja"); /** Locale which represents the Korean language. */ public static final Locale KOREAN = new Locale("ko"); /** Locale which represents the Chinese language. */ public static final Locale CHINESE = new Locale("zh"); /** Locale which represents the Chinese language as used in China. */ public static final Locale SIMPLIFIED_CHINESE = new Locale("zh", "CN"); /** * Locale which represents the Chinese language as used in Taiwan. * Same as TAIWAN Locale. */ public static final Locale TRADITIONAL_CHINESE = new Locale("zh", "TW"); /** Locale which represents France. */ public static final Locale FRANCE = new Locale("fr", "FR"); /** Locale which represents Germany. */ public static final Locale GERMANY = new Locale("de", "DE"); /** Locale which represents Italy. */ public static final Locale ITALY = new Locale("it", "IT"); /** Locale which represents Japan. */ public static final Locale JAPAN = new Locale("ja", "JP"); /** Locale which represents Korea. */ public static final Locale KOREA = new Locale("ko", "KR"); /** * Locale which represents China. * Same as SIMPLIFIED_CHINESE Locale. */ public static final Locale CHINA = SIMPLIFIED_CHINESE; /** * Locale which represents the People's Republic of China. * Same as CHINA Locale. */ public static final Locale PRC = CHINA; /** * Locale which represents Taiwan. * Same as TRADITIONAL_CHINESE Locale. */ public static final Locale TAIWAN = TRADITIONAL_CHINESE; /** Locale which represents the United Kingdom. */ public static final Locale UK = new Locale("en", "GB"); /** Locale which represents the United States. */ public static final Locale US = new Locale("en", "US"); /** Locale which represents the English speaking portion of Canada. */ public static final Locale CANADA = new Locale("en", "CA"); /** Locale which represents the French speaking portion of Canada. */ public static final Locale CANADA_FRENCH = new Locale("fr", "CA"); /** * Compatible with JDK 1.1+. */ private static final long serialVersionUID = 9149081749638150636L; /** * The language code, as returned by getLanguage(). * * @serial the languange, possibly "" */ private String language; /** * The country code, as returned by getCountry(). * * @serial the country, possibly "" */ private String country; /** * The variant code, as returned by getVariant(). * * @serial the variant, possibly "" */ private String variant; /** * This is the cached hashcode.
