Similar in com/paypal/android/foundation/i18n/model/moneyvalue/LocaleCurrency.java

    public Currency getCurrencyForCode(String str) {
        r1 = null;
        for (Currency currency2 : getCurrency()) {
            if (currency2.getCode().equalsIgnoreCase(str)) {
                break;
            }
        }
        return currency2;
    }
