java.util
public final class Locale extends Object implements Serializable, Cloneable
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.country (or user.region), and user.variant, defaulting to "en_US". 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.

Object.clone()
but does not throw
a CloneNotSupportedException
. Why anyone would
use this method is a secret to me, since this class is immutable.
Returns: the clone
Parameters: obj the other locale
Returns: true if obj is equal to this
Returns: the installed locales
Returns: country code portion of this locale, or an empty String
Returns: the default locale for this virtual machine
getDisplayCountry(Locale.getDefault());
Returns: the country name of this locale localized to the given locale, with the ISO code as backup
Gets the name of the country specified by this locale, in a form suitable
for display to the user. If possible, the display name will be localized
to the specified locale. For example, if the locale instance is
Locale.GERMANY
, and the specified locale is Locale.UK
,
the result would be 'Germany'. Using the German locale would instead give
'Deutschland'. If the display name can not be localized to the supplied
locale, it will fall back on other output in the following order:
If the country is unspecified by this locale, then the empty string is returned.
Parameters: inLocale the locale to use for formatting the display string.
Returns: the country name of this locale localized to the given locale, with the default locale, English and the ISO code as backups.
Throws: NullPointerException if the supplied locale is null.
getDisplayLanguage(Locale.getDefault());
Returns: the language name of this locale localized to the default locale, with the ISO code as backup
Gets the name of the language specified by this locale, in a form suitable
for display to the user. If possible, the display name will be localized
to the specified locale. For example, if the locale instance is
Locale.GERMANY
, and the specified locale is Locale.UK
,
the result would be 'German'. Using the German locale would instead give
'Deutsch'. If the display name can not be localized to the supplied
locale, it will fall back on other output in the following order:
If the language is unspecified by this locale, then the empty string is returned.
Parameters: inLocale the locale to use for formatting the display string.
Returns: the language name of this locale localized to the given locale, with the default locale, English and the ISO code as backups.

Returns: String version of this locale, suitable for display to the user
The returned String will be one of the following forms:
language (country, variant) language (country) language (variant) country (variant) language country variant
Parameters: locale locale to use for formatting
Returns: String version of this locale, suitable for display to the user
getDisplayVariant(Locale.getDefault());
Returns: the variant code of this locale localized to the given locale, with the ISO code as backup
