1.Client端

import java.net.* ;import java.io.* ;public class Client {    public static void main(String[] args) throws Exception {                Socket s = new Socket("localhost",8888);                //向伺服器發送訊息        InputStreamReader r = new InputStreamReader(System.in);        BufferedReader br = new BufferedReader(r);        System.out.println("Input your want to write : " );        String msg = br.readLine();                OutputStream os = s.getOutputStream();                DataOutputStream ds = new DataOutputStream(os);        ds.writeUTF(msg);                //接受來自伺服器的訊息        InputStream r1 = s.getInputStream();        DataInputStream dis = new DataInputStream(r1);        String serverMsg = dis.readUTF();        System.out.println("Reverse the Server massage is : " + serverMsg );                br.close();        s.close();    }}

 

2.Server端

 1 import java.net.*; 2 import java.io.* ; 3  4 public class Server { 5     public static void main(String[] args) throws Exception { 6         ServerSocket serverSocket = new ServerSocket(8888); 7         while(true) { 8              9             //接受用戶端訊息10             Socket socket = serverSocket.accept();11             System.out.println("a client connect this server !");12             InputStream r = socket.getInputStream();13         14             DataInputStream dis = new DataInputStream(r);15             String clientMsg = dis.readUTF();16             System.out.println("send to this server : " + clientMsg);17             18             //向用戶端回複訊息19             BufferedReader input = new BufferedReader(20                 new InputStreamReader(System.in)21             );22             String backMsg = input.readLine();23             OutputStream os = socket.getOutputStream();24             DataOutputStream dos = new DataOutputStream(os);25             dos.writeUTF(backMsg);26             input.close();27         }28     }29 }

以上代碼實現了點對點的通訊。
