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=fr -Duser.region= MyApp
    // Set language and country code
    > java -Duser.language=fr -Duser.region=CA 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.FRENCH);
    
    // Set the default locale to custom locale
    locale = new Locale("fr", "CA");
    Locale.setDefault(locale);
