[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。
package test9; public class Bus implements Transport{ @Override public void run() { System.out.print("Bus"); } }
package test9; public class Car implements Transport{ @Override public void run() { System.out.print("Car"); } }
package test9; public class LIqing extends Road{ public void drive() { transport.run(); System.out.println("行驶在沥青路"); } }
package test9; import java.util.Scanner; public class Main { public static void main(String[] args) { Transport transport = 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) { transport=(Transport)new Car(); road=(Road)new Shuini(); }else if(i==2) { transport=(Transport)new Car(); road=(Road)new LIqing(); }else if(i==3){ transport=(Transport)new Bus(); road=(Road)new Shuini(); }else if(i==4) { transport=(Transport)new Bus(); road=(Road)new LIqing(); }else { System.out.println("输入无效!"); } road.setTransport(transport); road.drive(); } }
package test9; public abstract class Road { protected Transport transport; public void setTransport(Transport tr) { this.transport=tr; } public abstract void drive(); }
package test9; public class Shuini extends Road{ public void drive() { transport.run(); System.out.println("行驶在水泥路"); } }
package test9; public interface Transport { public void run(); }
#include<iostream> using namespace std; class transport { public : transport(){} virtual ~transport(){} virtual void bedrive()=0; }; class bus :public transport { public: bus(){} virtual~bus(){} void bedrive(){cout<<"bus"<<endl;} }; class car :public transport { public: car(){} virtual~car(){} void bedrive(){cout<<"car"<<endl;} }; class road { public: road():_instance(NULL){} virtual~road(){} void settransport(transport *instance) { _instance=instance; } virtual void drive()=0; protected: transport *_instance; }; class shuini :public road { public: shuini(){} virtual~shuini(){} void drive(){cout<<"在水泥路上行驶的";_instance->bedrive();} }; class liqing :public road { public: liqing(){} virtual~liqing(){} void drive(){cout<<"在沥青路上行驶的";_instance->bedrive();} }; int main() { road *ro=new liqing; transport *tr=new bus; ro->settransport(tr); ro->drive(); delete ro; delete tr; ro=new shuini; tr=new car; ro->settransport(tr); ro->drive(); delete ro; delete tr; system("pause"); return 0; }
