        System.out.println("Currency Symbol With Locale:- " + us.getSymbol(Locale.US));
        Currency uk = Currency.getInstance(Locale.UK);
        System.out.println("\nCurrency Symbol:- " + uk.getSymbol());
        System.out.println("Currency Symbol With Locale:- " + uk.getSymbol(Locale.UK));
