Here are some specifications to guide your work: Charges for a suite, double-room and single-room are $499.00, S159.00 and $99.00 per day in Canadian Currency respectively. . The CheckOut button is used to trigger the calculation of the total room accommodation charges for the customer in Canadian Currency by default. The customer has an option to pay in U.S currency, and the user needs to input the currency exchange rate for the calculation of the payment in U.S. currency Your applet program should also be intelligent enough to trigger the calculation automatically when the user switches from the payment option in U.S. currency back to Canadian currency
