CurrencyFormatter.java

// Given a double-precision number, payment, denoting an amount of money, 
// use the NumberFormat class' getCurrencyInstance method to convert payment 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 formattedPayment is payment formatted according to the appropriate Locale's currency.
