java第三次作業：Java與socket實現

//用戶端程式1：ChatClient.java<pre name="code" class="java">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(4000);System.out.println("準備好了。退出輸入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.println(line);os.flush();System.out.println("Server:" + line);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);}}}

//用戶端程式2：ChatServer.java

import java.io.*;import java.net.*;public class CgatClient {public static void main(String[]args){try{Socket socket = new Socket("127.0.0.1",4000);System.out.println("輸入你要說的話，如果要退出輸入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("CatClient:"+ readline);System.out.println("Server:" + is.readLine());readline = sin.readLine();}os.close();is.close();socket.close();}catch(Exception e){System.out.println("Error" + e);}}}

//實現結果就是無論在那個程式所編譯出來的對話方塊，你在裡面輸入你要說的話，就會在另外一個對話方塊顯示出來。此兩個小程式實現的是簡單對話交流。

//該對話方塊的結束時輸入bye，即會話結束。
