软件设计模式————（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 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();
}
