java网络编程（二）

客户端程序：

package net;

import java.io.OutputStream;
import java.net.Socket;

/**
 * Created by hu on 2015/11/8.
 */
public class client {
    public static void main(String[] args)throws Exception{
        connectServer();
    }
    public static void connectServer() throws Exception{
        Socket socket=new Socket("127.0.0.1",8089);
        OutputStream os=socket.getOutputStream();
        os.write("my name is hujingwei".getBytes());
        //关闭socket的输出流
        socket.shutdownOutput();
        socket.close();
    }
}

server端程序：

package net;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

/**
 * Created by hu on 2015/11/8.
 */
public class Server {
    public static void main(String[] args)throws Exception{
        ServerSocket server=new ServerSocket(8089);
        while(true){
            acceptClient(server);
        }
    }
    public static  void acceptClient(ServerSocket server)throws Exception{
        System.out.println("Before accept");
        /*
        * ServerSocket中的accept()方法在没有接收到client的socket的时候，将一直处于阻塞状态（即后面的代码不执行）
        * 只有当接收到client的一个socket的时候，后面的代码才会继续执行。
        * */
        Socket socket=server.accept();
        System.out.println("After accept");
        InputStream is=socket.getInputStream();
        BufferedReader br=new BufferedReader(new InputStreamReader(is));
        String s=br.readLine();
        System.out.println(s);
        socket.isInputShutdown();
        socket.close();
    }
}
