Java Locale
A locale represents a geographic, political or cultural region.
Locales are frequently defined by a language/country combination.
The language is usually represented using a lowercase two-letter
designator defined by ISO
639 (e.g. en for English, fr for French,
zh for Chinese). The country is typically represented
using uppercase two-letter designators defined by ISO
3166 (e.g. US for the United States, FR
for France). The representation of the US locale would be en_US .
The third argument, the Variant , can be vendor specific
(ex. Texas or California as subsets of en_US). Create a Locale
object using one of the three constructors in this class:
Locale(String language)
Locale(String language, String country)
Locale(String language, String country, String variant)
Java has a number of functions that facilitate international programming.
One such class is the java.util.Locale class. This
class maintains a static default locale that can be set and queried.
The Locale class does not implement any internationalization
behaviors. It serves as a locale identifier for those classes that
do. The application should make a runtime determination of user
locale. This determination can be made from any of the following
techniques:
java.util.Locale class method Locale.getDefault()
returns the default locale object inherited from the host system.
- User selected via a mechanism built into the application that
allows the user to select the language. Here you would use the
Locale.setDefault() method.
- Explicitly specify a locale based on personalization settings.
Here again you would use the
Locale.setDefault()
method.
Please see the Java Locale example
for more information on usage.
