HackerRank Java Currency Formatter - Problem Statement

Given a double-precision number, payment, denoting an amount of money, use the NumberFormat class' getCurrencyInstance method to convert the 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 (code-box)

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).

Input Format

A single double-precision number denotes payment.

Constraints

0 <= payment <= 10^9

Output Format

On the first line, print US: u where u is payment formatted for US currency.

On the second line, print India: i where i is payment formatted for the Indian currency.

On the third line, print China: c where c is payment formatted for Chinese currency.

On the fourth line, print France: f, where f is payment formatted for French currency.

Sample Input

12324.134 (code-box)

Sample Output

US: $12,324.13 India: Rs.12,324.13 China: ￥12,324.13 France: 12 324,13 € (code-box)
