下面的程序说明了getCurrencyCode()方法的工作。

程序 1 :

// 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("INR");
  
        // Getting the currency code
        String currency_code
            = curr_ency.getCurrencyCode();
        System.out.println("Currency Code of India is: "
                           + currency_code);
    }
}

输出:

Currency Code of India is: INR

程序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);
    }
}

输出:

Currency Code of USA is: USD

程序3： 对于一个无效的货币代码。

// Java Code to illustrate getCurrencyCode() method
  
import java.util.*;
  
public class Currency_Demo {
    public static void main(String[] args)
    {
        try {
  
            // Creating a currency with the code
            Currency curr_ency
                = Currency.getInstance("USDA");
  
            // Getting the currency code
            String currency_code
                = curr_ency.getCurrencyCode();
            System.out.println("Invalid Currency Code: "
                               + currency_code);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

输出:
