public static void storeCredentials(String username, String password) {
    Preferences prefs = Preferences.userRoot().node("credentials");
    prefs.put("username", username);
    prefs.put("password", password);
}

public static String[] getCredentials() {
    Preferences prefs = Preferences.userRoot().node("credentials");
    String username = prefs.get("username", "");
    String password = prefs.get("password", "");
    return new String[]{username, password};
}
