java.util.Currency.getInstance supports only ISO 4217 currency codes, not currency numbers. However, you can retrieve all currencies using the getAvailableCurrencies method, and then search for the one with code 840 by comparing the result of the getNumericCode method.

Like this:

public static Currency getCurrencyInstance(int numericCode) {
    Set<Currency> currencies = Currency.getAvailableCurrencies();
    for (Currency currency : currencies) {
        if (currency.getNumericCode() == numericCode) {
            return currency;
        }
    }
    throw new IllegalArgumentException("Currency with numeric code "  + numericCode + " not found");
}
