JAVA聊天服务器代码 java服务端编程

为java聊天室代码加详细注释,并说明设计思路。好的加100分。

编一个简单的java聊天程序,但是运行时服务器和客户端都出错

给你简单修改了一下,你看看吧

import java.io.*;

import java.net.*;

import java.util.*;

import java.text.*;

public class ChatClient {

public static void main(String[] args) throws Exception {

Socket c = new Socket("127.0.0.1", 1123);

while (true) {

Date now = new Date();

DateFormat d = DateFormat.getDateTimeInstance();

String time = d.format(now);

PrintWriter OutputS = new PrintWriter(c.getOutputStream());

BufferedReader say = new BufferedReader(new InputStreamReader(System.in));

String Csay = say.readLine();

System.out.println("Client:" + String.valueOf(c.getLocalPort()) + Csay + time);

OutputS.println("Client:" + String.valueOf(c.getLocalPort()) + Csay + time);

OutputS.flush();

BufferedReader InputS = new BufferedReader(new InputStreamReader(c.getInputStream()));

System.out.println(InputS.readLine());

}

}

}

、、、、、、、、、、、、、、、、

import java.io.*;

import java.net.*;

import java.text.*;

import java.util.*;

public class ChatServer {

private static int PORTNUM = 1123;// 定义程序使用的端口号PORTNUM

public static void main(String args[]) throws Exception {

ServerSocket s = new ServerSocket(PORTNUM);

while (true) {

Socket s1 = s.accept();

BufferedReader InputS = new BufferedReader(new InputStreamReader(s1.getInputStream()));

System.err.println();

System.out.println(InputS.readLine());

Date now = new Date();

DateFormat d = DateFormat.getDateTimeInstance();

String time = d.format(now);

PrintWriter OutputS = new PrintWriter(s1.getOutputStream());

BufferedReader say = new BufferedReader(new InputStreamReader(System.in));

String Ssay = say.readLine();

OutputS.println("Server" + String.valueOf(s1.getLocalPort()) + Ssay + time);

OutputS.flush();

System.out.println("Server" + String.valueOf(s1.getLocalPort()) + Ssay + time);

}

}

}

说一下你的程序出现的原因吧!

你的客户端与程序段在开始运行都在监听对方发来的消息,当什么都不会有了,因为对方都在等着接受消息呢,这样就造成了死锁
