TCP/IP 编程

所谓网络编程就是成对的。。。互相连接。。。so有两个代码，一个是客户端，一个是服务端。。。这两个代码是最简单的，模板型的，对我这初学者来说，感觉不简单

代码仍在这里就为了留下一个脚印。。。一个我深深踏过的。。。

package heng.java.TCP;import java.io.DataInputStream;import java.io.IOException;import java.net.ServerSocket;import java.net.Socket;public class TCPServer {public static void main(String[] args) {try {ServerSocket ss = new ServerSocket(8888);//通过6666这个端口号，来监听客户端的连接while(true){Socket s = ss.accept();DataInputStream dis = new DataInputStream(s.getInputStream());System.out.println(dis.readUTF());//阻塞式。（效率不高）UTF会一直等Client写东西过来dis.close();s.close();//System.out.println("A client connect");}} catch (IOException e) {e.printStackTrace();}}}

package heng.java.TCP;import java.io.DataOutputStream;import java.io.IOException;import java.io.OutputStream;import java.net.Socket;import java.net.UnknownHostException;public class TCPClient {public static void main(String[] args) {try {//申请连接Socket s = new Socket("192.168.1.102",8888);OutputStream os = s.getOutputStream();DataOutputStream dos = new DataOutputStream(os);dos.writeUTF("Hello server!");dos.flush();dos.close();s.close();} catch (UnknownHostException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}
