11.4实验9：桥接模式

[实验任务一]：两个维度的桥接模式

用桥接模式实现在路上开车这个问题，其中，车可以是car或bus，路可以是水泥路或沥青路。

实验要求：

1. 画出对应的类图；

 

 

2.提交源代码；

public class AsphaltRoad extends Road{

   public AsphaltRoad(Vehicle vehicle) {

       super(vehicle);

   }



   @Override

   public void driveOnRoad() {

       super.vehicle.drive();

       System.out.println("沥青路");

   }

}

 

 

 

public class Bus implements Vehicle{



   @Override

   public void drive() {

       System.out.println("公交车行驶在");

   }

}

 

 

 

public class Car implements Vehicle{

   @Override

   public void drive() {

       System.out.println("小轿车行驶在");

   }

}

 

 

 

public class CementRoad extends Road{



   public CementRoad(Vehicle vehicle) {

       super(vehicle);

   }



   @Override

   public void driveOnRoad() {

       super.vehicle.drive();

       System.out.println("水泥路");

   }

}

 

 

 

public class Client {

   public static void main(String[] args) {

       Road road = new AsphaltRoad(new Car());

       road.driveOnRoad();

       System.out.println("**************************************************");

       Road road1 = new CementRoad(new Bus());

       road1.driveOnRoad();

   }

}

 

 

 

public abstract class Road {

   protected Vehicle vehicle;

   public Road(Vehicle vehicle){

       this.vehicle = vehicle;

   }

   public abstract void driveOnRoad();

}

 

 

 

public interface Vehicle {

   public void drive();

}

 

3.注意编程规范。
