Output:
Currency Code of India is: INR
Program 2:
// Java Code to illustrate// getCurrencyCode() method  import java.util.*;  public class Currency_Demo {    public static void main(String[] args)    {          // Creating a currency with the code        Currency curr_ency            = Currency.getInstance("USD");          // Getting the currency code        String currency_code            = curr_ency.getCurrencyCode();        System.out.println("Currency Code of USA is: "                           + currency_code);    }} |
Output:
Currency Code of USA is: USD
Program 3: For an invalid Currency Code.
