作业的目标

目标1：Socket简单应用。把教材P238-230中例11-5代码输入到我们的代码编辑器，调试并运行（80分）。

P238客户端程序

import java.io.*;import java.net.*;public class ChatClient {public static void main(String args[]){try{Socket socket=new Socket("127.0.0.1",4001);System.out.println("输入你要说的话，如果要退出输入bye");BufferedReader sin=new BufferedReader(new InputStreamReader(System.in));PrintWriter os=new PrintWriter(socket.getOutputStream());BufferedReader is=new BufferedReader(new InputStreamReader(socket.getInputStream()));String readline;readline =sin.readLine();while(! readline.equals("bye")){os.println(readline);os.flush();System.out.println("Client:"+readline);System.out.println("Server:"+is.readLine());readline=sin.readLine();}os.close();is.close();socket.close();}catch(Exception e){System.out.println("Error"+e);}}}

P238-230 服务器端程序

import java.io.*;import java.net.*;import java.applet.Applet;public class ChatServer {public static void main(String args[]){try{ServerSocket server=null;try{server=new ServerSocket(4001);System.out.println("准备好了，退出输入bye");}catch(Exception e){System.out.println("can not listen to:"+e);}Socket socket=null;try{socket=server.accept();}catch(Exception e){System.out.println("Error."+e);}String line;BufferedReader is=new BufferedReader(new InputStreamReader(socket.getInputStream()));PrintWriter os=new PrintWriter(socket.getOutputStream());BufferedReader sin=new BufferedReader(new InputStreamReader(System.in));System.out.println("Client:"+is.readLine());line=sin.readLine();while(! line.equals("bye")){os.print(line);os.flush();System.out.println("Client:"+is.readLine());line=sin.readLine();}os.close();is.close();socket.close();server.close();}catch(Exception e){System.out.println("Error:"+e);}}}
