    public static void showPriceInGBP(double price, double rate) {
        double princeInGBP = price * rate;
        NumberFormat GBP = NumberFormat.getCurrencyInstance(Locale.UK);
        System.out.printf("Price in GBP : %s %n", GBP.format(princeInGBP));

    }

    /** * @return FX exchange rate for USD * @param currency */
    public static double getExchangeRate(String currency) {
        switch (currency) {
        case "USD":
            return 1;
        case "JPY":
            return 102.53;
        case "GBP":
            return 0.60;
        case "EURO":
            return 0.73;
        default:
            throw new IllegalArgumentException(String.format(
                    "No rates available for currency %s %n", currency));
        }
    }
}
