[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。

1. 源代码
1.Car.java
package test9;
public class Car implements Vehicle{
@Override
public void drive() {
System.out.println("小轿车行驶在");
}
}
2.CementRoad.java
package test9;
public class CementRoad extends Road{
public CementRoad(Vehicle vehicle) {
super(vehicle);
}
@Override
public void driveOnRoad() {
super.vehicle.drive();
System.out.println("水泥路");
}
}
3.Client.java
package test9;
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();
}
}
4.Road.java
package test9;
public abstract class Road {
protected Vehicle vehicle;
public Road(Vehicle vehicle){
this.vehicle = vehicle;
}
public abstract void driveOnRoad();
}
5.Vehicle.java
package test9;
public interface Vehicle {
public void drive();
}
6.AsphaltRoad.java
package test9;
public class AsphaltRoad extends Road{
public AsphaltRoad(Vehicle vehicle) {
super(vehicle);
}
@Override
public void driveOnRoad() {
super.vehicle.drive();
System.out.println("沥青路");
}
}
7.Bus.java
package test9;
public class Bus implements Vehicle{
@Override
public void drive() {
System.out.println("公交车行驶在");
}
}
