Java 实战：交通工具类（Vehicle）及子类小汽车（Car）、卡车（Truck）的继承与实现

```java // vehicles类 class vehicles { String brand; String color; public vehicles(String brand, String color) { this.brand = brand; this.color = color; } public void run() { System.out.println("我已经开动了"); } public void showinfo() { System.out.println("品牌：" + brand); System.out.println("颜色：" + color); } } // car类 class car extends vehicles { int seats; public car(String brand, String color, int seats) { super(brand, color); this.seats = seats; } public void showcar() { System.out.println("小汽车信息："); showinfo(); System.out.println("座位数：" + seats); } } // truck类 class truck extends vehicles { float load; public truck(String brand, String color, float load) { super(brand, color); this.load = load; } public void showtruck() { System.out.println("卡车信息："); showinfo(); System.out.println("载重：" + load); } } public class Main { public static void main(String[] args) { car myCar = new car("Toyota", "Red", 5); myCar.showcar(); myCar.run(); truck myTruck = new truck("Ford", "Blue", 5000); myTruck.showtruck(); myTruck.run(); } } ``` ######[AI写代码神器 | 919点数解答 | 2024-09-20 08:06:42]
