java聊天室思路是什么，报告怎么写

import java.net.Socket;import java.io.*;public class Client extends Thread \\\/\\\/ 定义一个Client线程类{ private Socket m_socket;\\\/\\\/ 定义一个socket对象; public Client()\\\/\\\/ 默认构造函数 { } public boolean ConnToServer(String strip, int port) throws Exception\\\/\\\/ 连接指定IP和端口的服务器，如果连接成功，返回true,否则返回false。

{ m_socket = new Socket(strip, port); return m_socket.isClosed(); } class SendData extends Thread { Socket m_sendso; BufferedReader in; OutputStream out; public SendData(Socket so) { this.m_sendso = so; this.start(); } public void run() { \\\/\\\/ 不断从键盘获取字符串发送给服务器 String msg; while (true) { try { in = new BufferedReader(new InputStreamReader(System.in)); out = m_sendso.getOutputStream(); msg = in.readLine(); BufferedWriter bWriter = new BufferedWriter(new OutputStreamWriter(out)); \\\/\\\/ new ObjectOutputStream(out).writeUTF(msg); bWriter.write(msg); } catch (IOException e) { \\\/\\\/ TODO Auto-generated catch block e.printStackTrace(); } } } } class RecvData extends Thread { Socket m_recvso; BufferedReader in; OutputStream out; public RecvData(Socket so) { this.m_recvso = so; start(); } public void run() { \\\/\\\/ 不断从服务器读取数据，并打印出来 while(true) try { in = new BufferedReader(new InputStreamReader(m_recvso.getInputStream())); System.out.println(in.readLine()); } catch (IOException e) { \\\/\\\/ TODO Auto-generated catch block e.printStackTrace(); } } }}好长时间没网络编程了，试试吧
