 Java Currency Formatter

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.

 

Note: India does not have a built-in Locale, so you must construct one where the language is en (i.e., English).
