爪哇问题;无法将活动添加到数组列表<???>需要帮助

Question

我正在准备星期一的测试，但是没有答案。到目前为止，我做得很好，但现在被困了。我无知该怎么办。搜索了互联网上的年龄，但我想我错过了一个小东西。

也许你们可以帮助我？

问题：我需要将活动放在日间播放的ArrayList＆lt; ...>中并将它们打印出来，我不知道该怎么做。

我已经尝试了arraylist整数字符串，我不知道* *我这样做：pGATAGESIMULATION中的目标运行模拟（）。

bicycle.java and parter.java并不是我认为在这里展示的真正必要。

希望你们中的一些人能帮助我！预先感谢!!!!!

Answer 1

dayplan被声明为

private ArrayList<Vehicle> dayplan;

，您可以在没有任何参数的情况下调用添加方法。

dayplan.add();

这就是导致编译误差的原因。

您需要通过IT参数，vehicle。

dayplan.add(vehicle);

Answer 2

问题是

dayplan.add(); 

您应该添加车辆

所以将其更改为

dayplan.add(vehicle);
