TCP通信程序的练习2

• 客户端:发送数据,数据来自与键盘录入,直到输入的数据是886,发送数据结束
  ClientDeom类

package Demo;



import java.io.*;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientDemo {
    public static void main(String[] args) throws IOException {
        //建立客户端
        Socket socket = new Socket(InetAddress.getByName("sgs").getHostAddress(),1110);

        //获取输出流,写数据,采取键盘写数据(本次采取用字符缓冲输出流写一行)
        //写数据
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
        String line;
        System.out.println("请输入要发送给服务器的数据");
        while((line=br.readLine())!=null) {
            if ("886".equals(line)){
                break;
            }else{
                bw.write(line);
                bw.newLine();
                bw.flush();
            }
        }

        //释放资源
        socket.close();

    }
}

• 服务器:接收数据，在控制台输出
  Server类

package Demo;


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

public class ServerDemo {
    public static void main(String[] args) throws IOException {
        //建立服务器
        ServerSocket serverSocket = new ServerSocket(1110);

        //侦听要连接到此客户端套接字并接受它
        Socket socket = serverSocket.accept();

        //获取输入流,读数据(本次采取用字符缓冲输入流写一行)
        BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));

        String line;
        while ((line=br.readLine())!=null){
            System.out.println("收到客户端的数据");
            System.out.println(line);
        }
    }
}
