第8次实验--组合模式、代理模式实验

实验8—组合模式、代理模式实验学号：123012012137姓名：张超红实验目的：加深对组合模式、代理模式原理的理解实验环境：C#.Net/VC++.Net或MyEclipse(Java)等实验内容（一）：使用组合模式设计一个杀毒软件框架，该软件既可以对一个文件夹杀毒，也可以对一个文件杀毒，文件种类包括文本文件、图片文件、视频文件。

绘制类图并编程实现。

⑴实验过程：①、构建实现场景，画出UML类图②、实现代码,见演示源码public abstract class AntiVirus {public void killVirus(){}}import java.util.ArrayList;public class Folder extends AntiVirus {private ArrayList fileList= new ArrayList();public void folder(AntiVirus fileName){fileList.add(fileName);}public void killVirus(){for(Object object:fileList){System.out.println(object.getClass().getName());((AntiVirus)object).killVirus();}}}public class ImageFile extends AntiVirus {public void killVirus(){System.out.println("ImageFile杀毒中");}}public class TextFile extends AntiVirus {public void killVirus(){System.out.println("TextFile杀毒中");}}public class VideoFile extends AntiVirus {public void killVirus(){System.out.println("VideoFile杀毒中");}}public class Client {/*** @param args*/public static void main(String[] args) {AntiVirus file1,file2,file3,file4,file5,file6;Folder floder1,floder2,floder3;file1=new ImageFile();file2=new TextFile();file3=new VideoFile();floder1 =new Folder();floder1.folder(file1);floder1.folder(file2);floder1.folder(file3);file4=new ImageFile();file5=new TextFile();file6=new VideoFile();floder2=new Folder();floder2.folder(file1);floder2.folder(file2);floder2.folder(file3);floder3=new Folder();floder3.folder(floder1);floder3.folder(floder2);floder3.killVirus();}}实验内容（二）：某信息咨询公司推出收费的在线商业信息查询模块，需要对查询用户进行身份验证，并记录查询日志，以便根据查询次数收取查询费用，现使用代理模式设计该系统。

⑴实验过程：①构建实现场景，画出UML类图②实现代码package agent;** @author张超红**/public class User {public User() {// TODO自动生成的构造函数存根}private String userName;private String password;//是否被允许private boolean isPermission;//查询次数Integer selectCount;//查询费用private double selectOffFees;public String getUserName() {return userName;}public void setUserName(String userName) {erName = userName;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public boolean isPermission() {return isPermission;}public void setPermission(boolean isPermission) { this.isPermission = isPermission;}public Integer getSelectCount() {return selectCount;}public void setSelectCount(Integer selectCount) { this.selectCount = selectCount;public double getSelectOffFees() {return selectOffFees;}public void setSelectOffFees(double selectOffFees) { this.selectOffFees = selectOffFees;}}package agent;/**** @author张超红**/public class PermissionProxy implements AbstractCompony {private User user;private RealCompony permission=new RealCompony();public PermissionProxy() {// TODO自动生成的构造函数存根}/* （非 Javadoc）* @see agent.AbstractCompony#selectInfor()*/@Overridepublic void selectInfor() {// TODO自动生成的方法存根if(user.isPermission()){if(user.getSelectCount()>0){permission.selectInfor();user.selectCount--;if(user.selectCount<=0){user.setPermission(false);}}System.out.println("您查询次数已经到达上限，请缴费...");}else{System.out.println("要在本系统中查询商业信息请先注册登录...");}public User construct(){return new User();}}package agent;/**** @author张超红**/public interface AbstractCompony {//查询用户信息public void selectInfor();}package agent;public class RealCompony implements AbstractCompony {public RealCompony() {// TODO自动生成的构造函数存根}/* （非 Javadoc）* @see agent.AbstractCompony#selectInfor()*/@Overridepublic void selectInfor() {// TODO自动生成的方法存根System.out.println("用户正在查询商业信息...");}}package agent;/*** @author张超红**/public class Client {public Client() {// TODO自动生成的构造函数存根}public static void main(String[] args) { RealCompony permission=new RealCompony();PermissionProxy per=new PermissionProxy();User user=new User();user.setSelectCount(2);user.setPermission(true);permission.selectInfor();}}⑵实验讨论（效果分析）:。
