There are two ways to change the default
locale. The first is to set it on the command line:
> java
-Duser.language=2-char-language-code -Duser.region=2-char-country-code
MyApp
// Set only language code
> java -Duser.language=en
-Duser.region= MyApp
// Set language and country code
> java
-Duser.language=en -Duser.region=US MyApp
The second way to change the
default locale is to call Locale.setDefault():
// Get default
locale
Locale locale = Locale.getDefault();
// Set the default locale
to pre-defined locale
Locale.setDefault(Locale.US);
// Set the default
locale to custom locale
locale = new Locale("en",
"US");
Locale.setDefault(locale);
