Question

@Override
public org.joda.money.Money computeCharge(org.joda.time.DateTime from,
                                      org.joda.time.DateTime to){

}

从界面复制的说明：Parkable

计算这段时间内停车的费用。指定者：接口Parkable中的computeCharge 参数：from - 车辆进入的时间。至 - 车辆释放的时间。退货：这里的停车费用。

例如，我们每小时收费8美元。

private void updateCharge() {
    jtc.setText(jcb.getSelectedItem() + " for " + jtf.getText());

    DateTime from = new DateTime(arriveTime.getDate());
    DateTime to = new DateTime(departTime.getDate());
    Period p = new Period(from, to);

    Parkable pk = (Parkable) jcb.getSelectedItem();
    pk.computeCharge(from, to);
    jtc.setText(pk.computeCharge(from, to).toString());
    System.out.println(jcb.getSelectedItem() + " for " + jtf.getText()
            + " costs " + pk.computeCharge(from, to));
}

第二个编码是我的计算器面板。因此，接口实例pk实现了computeCharge方法。然后，System.out.println（...“cost”+ pk.computeCharge（from，to））。请帮帮我。

Answer 1

我写了这样的东西;

public static void main(String[] args) {
    DateTime to = new DateTime().minusHours(3).minusSeconds(30);
    DateTime from = new DateTime();
    System.out.println("Total Amount is = " + computeCharge(from, to));
}

public static Money computeCharge(DateTime from, DateTime to) {
    int hourlyAmount = 8;
    Money result = Money.of(CurrencyUnit.USD, hourlyAmount);
    Minutes minutes = Minutes.minutesBetween(to, from);
    return result.multipliedBy(minutes.getMinutes() / 60);
}

您可以针对您的情况进行修改。

输出是;

Total Amount is = USD 24.00
