Java

这是JAVA入门第二季最后的作业。
还有很多可以修改的地方，比如对异常的处理等等。写的比较匆忙，而且第三季还没开始学，所以就先暂时放下了。
以下是代码：

package com.zc;

    //导入车辆信息
    public static keChe[] aa={new keChe("斯柯达Yeti",200,5),new keChe("奔驰GLC   ",280,5),new keChe("宝马Z4    ",480,2)};
    public static huoChe[] bb={new huoChe("解放J6P   ",400,6),new huoChe("欧曼GTL   ",420,8),new huoChe("沃尔沃FH16",420,9)};
    public static piKa[] cc={new piKa("风骏5     ",150,2,3),new piKa("福特F650  ",180,2,3)};
