Given a double-precision number, , denoting an amount of money, use the NumberFormat class' getCurrencyInstance method to convert  into the US, Indian, Chinese, and French currency formats. Then print the formatted values as follows:

US: formattedPayment
India: formattedPayment
China: formattedPayment
France: formattedPayment

where  is  formatted according to the appropriate Locale's currency.
