殺毒軟件：
殺毒軟件是每一臺電腦不可少的應(yīng)用軟件之一，現(xiàn)在我來研究 一下殺毒軟件的整個工作流程吧。。。首先要明確殺毒軟件的目的是什么，怎么樣才能實現(xiàn)這一目的。。。
殺毒軟件是客戶在通過掃描自己的電腦里的每一個文件，然后與殺毒軟件服務(wù)器病毒庫里的病毒相比較，如果你電腦里有和服務(wù)器中文件相同的，殺毒軟件就視為是病毒，然后有用戶選擇是否要把掃描出來的文件刪除。。。。下面是我用Java語言來實現(xiàn)這個功能的。。。希望對大家有所感悟。現(xiàn)在說說我的具體實現(xiàn)的步驟吧。
服務(wù)器代碼：

import com.dr.bean.Virus;
public class Server {
public static List<Virus> virusList = new ArrayList<Virus>();
public static void main(String[] args) throws IOException {
ServerSocket server = null;
//輸出肯定使用打印流
PrintStream out = null;
//服務(wù)器肯定也要接收數(shù)據(jù)
BufferedReader buf = null;
//實例化一個服務(wù)器的監(jiān)聽端
server = new ServerSocket(8888);
//可以用一種死循環(huán)的方式接收內(nèi)容
System.out.println("---------服務(wù)器已經(jīng)啟動----------");

//初始化暗殺名單
//List<Virus> virusList = getVirusList();
while(true){
//不斷接收內(nèi)容

//準備好向客戶端輸入內(nèi)容

//而且客戶端要有輸入給服務(wù)器端

//接收客戶端發(fā)送過來的內(nèi)容
String str = buf.readLine();
System.out.println("server receive data is:"+str);
String virus = "";
if("getVirusList".equals(str)){//組成暗殺協(xié)議,返回客戶端
for(Virus v :virusList){
virus += v.getName()+":";
}
out.println(virus);
}
//進行收尾工作
out.flush();
out.close();
buf.close();

首先要啟動服務(wù)器，殺毒軟件才能夠正常的工作。。。。。。。
病毒類：
package com.dr.bean;
public class Virus{
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
