Use

.
Discussion
Classes that provide formatting services, such as
DateFormat
and
NumberFormat
, provide an
overloaded
getInstance()
method that can be called either with no arguments or with a
Locale
argument.
To use these, you can employ one of the predefined locale variables provided by the
Locale
class, or you can construct your own
Locale
object giving a language code and a country
code:
Locale locale1 = Locale.FRANCE; // predefined
Locale locale2 = new Locale("en", "UK"); // English, UK version
Either of these can be used to format a date or a number, as shown in class
UseLocales
:
