In C programming, the function 'setlocale()' and other APIs are called in 'main' (see here ). In Java, this is unnecessary. However, if you want to use a specific locale (e.g. a locale specified in a file), you can apply the specified locale to the whole of application with the following methods called in 'main':
public static void main(String[] args) {
Locale.setDefault(bundle.getLocale());
// *You need the method below for Swing APIs (JFileChooser .etc).
JComponent.setDefaultLocale(bundle.getLocale());
...
}
The classes listed below are internationalized. Methods of these classes
are affected by the locale.
