写在前面
只是我的Java课程的一个大作业，仅供参考。使用到的Java特性有：封装、继承、多态、包、GUI、Swing、集合类。耗时一周，一千行左右。
一、仿真模拟的具体要求
二、类的设计
考虑到程序仿真比较复杂，优先思考类与类之间的关联，下面用类图来描述。
2.1 抽象父类PubVehicles
PubVehicles作为抽象父类，有俩个子类分别是Iveco和Volvo，基本的成员变量在右侧，抽象方法在左侧。
2.2 Expressway类
Expressway类，放置在Expressway.java文件中，包含需要使用的变量，以及main方法和initialization方法。
2.3 Passenger类
Passenger类，有构造方法、上车等方法。右侧是成员变量，分别是是否在宝鸡站和目的地。
2.4 Timer类
Timer类，用于记录时间，以及刷新GUI界面，从而实现运动的画面。左侧是相关的方法，右侧是一些基本成员变量。
2.5 DisplayToolkit类
DisplayToolkit类主要运用GUI和Swing的组件，创建可视化用户界面。
三、图像显示
这里主要是让小车运动起来的实现，小车的PNG图片如下（背景透明）
images文件夹与src文件夹放置在同一目录下即可。
具体放置到GUI界面中基本上是八股文代码，如下所示(仅供演示）
复制代码
java
//right变量 图片路径 public Image right=Toolkit.getDefaultToolkit().createImage("images/Iveco_Right.png"); //lb和ii，将图片放置到JLabel上 JLabel lb=new JLabel(); ImageIcon ii=new ImageIcon(right); //设置 ii.setImage(ii.getImage().getScaledInstance(80, 80, Image.SCALE_DEFAULT));//缩放到80x80 lb.setToolTipText("Iveco "+this.number);//鼠标移到上面有信息显示 lb.setVisible(true); lb.setIcon(ii); Expressway.panel_cars.add(lb);
四、代码实现
完整代码、PNG素材、类图设计，请在公众号私信回复 [西宝高速公路] 获取，下面超长，最好不要翻阅。
