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;

3.注意编程规范。

 

 

1、类图

 

 

2、源代码

(1)  Bus.java

package test;

 

public class Bus implements Vehicle{

    @Override

    public void run() {

        System.out.print("Bus");   

    }

}

(2)  Car.java

package test;

 

public class Car implements Vehicle{

    @Override

    public void run() {

        System.out.print("Car");   

    }

}

(3)  liqing.java

package test;

 

 

public class liqing extends Road{

    public void drive() {

        vehicle.run();

        System.out.println("行驶在沥青路");

    }

}

(4)  Main.java

package test;

 

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        Vehicle vehicle = null;

        Road road = null;

        System.out.println("请选择:1、Car/水泥路  2、Car/沥青路  3、Bus/水泥路  4、Bus沥青路");

        Scanner input=new Scanner(System.in);

        int i=input.nextInt();

        if(i==1) {

            vehicle=(Vehicle)new Car();

            road=(Road)new Shuini();

        }else if(i==2) {

            vehicle=(Vehicle)new Car();

            road=(Road)new liqing();

        }else if(i==3){

            vehicle=(Vehicle)new Bus();

            road=(Road)new Shuini();

        }else if(i==4) {

            vehicle=(Vehicle)new Bus();

            road=(Road)new liqing();

        }else {

            System.out.println("输入无效!");

        }

        road.setVehicle(vehicle);

        road.drive();

    }

}

(5)  Road.java

package test;

 

public abstract class Road {

    protected Vehicle vehicle;

    public void setVehicle(Vehicle ve) {

        this.vehicle=ve;

    }

    public abstract void drive();

}

(6)  Shuini.java

package test;

 

public class Shuini extends Road{

    public void drive() {

        vehicle.run();

        System.out.println("行驶在水泥路");

    }

}

(7)  Vehicle.java

package test;

 

public interface Vehicle {

    public void run();

}
