Java Currency Class

Introduction

The Java Currency class represents a currency. Following are the important points about Currency −

  • Currencies are identified by their ISO 4217 currency codes.

  • The class is designed so that there's never more than one Currency instance for any given currency, this is the reason behind no public constructor.

Class declaration

Following is the declaration for java.util.Currency class −

public final class Currency
   extends Object
   implements Serializable

Getting All Available Currency Codes Example

The following example shows the usage of Java Currency getAvailableCurrencies() method to get a set of available currencies. We've created a set of avaiable currencies using getAvailableCurrencies() method and then printed each currency code. 

package com.tutorialspoint;

import java.util.Currency;
import java.util.Set;

public class CurrencyDemo {
   public static void main(String args[]) {

      Set<Currency> currencies = Currency.getAvailableCurrencies();

      System.out.println("Available Currencies: ");
      currencies.forEach(c -> System.out.print(c.getCurrencyCode() + " "));
   }
}

Let us compile and run the above program, this will produce the following result −
