After Internationalization

The source code for the internationalized program follows. Notice that the text of the messages is not hardcoded.

import java.util.*;

public class I18NSample {

    static public void main(String[] args) {

        String language;
        String country;

        if (args.length != 2) {
            language = new String("en");
            country = new String("US");
        } else {
            language = new String(args[0]);
            country = new String(args[1]);
        }

        Locale currentLocale;
        ResourceBundle messages;

        currentLocale = new Locale(language, country);

        messages = ResourceBundle.getBundle("MessagesBundle",
                                           currentLocale);
        System.out.println(messages.getString("greetings"));
        System.out.println(messages.getString("inquiry"));
        System.out.println(messages.getString("farewell"));
    }
}
