[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 Bus implements Vehicle
{
@Override
public void drive()
{
System.out.print("大巴");
}
}

 

public class Car implements Vehicle
{
@Override
public void drive()
{
System.out.print("小轿车");
}
}

 

public class CementRoad extends Road
{
public CementRoad(Vehicle vehicle)
{
super(vehicle);
}

@Override
public void driveOnRoad()
{
super.vehicle.drive();
System.out.println("行驶在水泥路");
}
}

 

public class main {
public static void main(String[] args) {
Road road = new CementRoad(new Car());
road.driveOnRoad();
}
}

 

public abstract class Road
{
protected Vehicle vehicle;

public Road(Vehicle vehicle)
{
this.vehicle = vehicle;
}

public abstract void driveOnRoad();
}

 

public class UnpavedRoad extends Road
{
public UnpavedRoad(Vehicle vehicle)
{
super(vehicle);
}

@Override
public void driveOnRoad()
{
super.vehicle.drive();
System.out.println("行驶在石子路");
}
}

 

public interface Vehicle {
public void drive();

}

3.注意编程规范。
