Required JARs on classpath:

  // Let’s create non-ISO currency, such as bitcoin

  // At first, this will throw UnknownCurrencyException MonetaryAmount moneys = Money.of(new BigDecimal(“0.1”), “BTC”);

  // This happens because bitcoin is unknown to default currency // providers System.out.println(Monetary.isCurrencyAvailable(“BTC”)); // false

  // We will build new currency using CurrencyUnitBuilder provided by org.javamoney.moneta CurrencyUnit bitcoin = CurrencyUnitBuilder .of(“BTC”, “BtcCurrencyProvider”) // Set currency code and currency provider name .setDefaultFractionDigits(2) // Set default fraction digits .build(true); // Build new currency unit. Here ‘true’ means // currency unit is to be registered and // accessible within default monetary context

  // Now BTC is available System.out.println(Monetary.isCurrencyAvailable(“BTC”)); // True
