TCP通信程序的练习3

• 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
  ClientDemo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 sgs = new Socket(InetAddress.getByName("sgs").getHostAddress(), 1110);
        //获取输出流,写数据,采取字符缓冲流(一次写入一行)
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(sgs.getOutputStream()));

        String line;
        System.out.println("请输入你要输入的数据");
        while((line= br.readLine())!=null){
            if ("886".equals(line)){
                break;
            }else {
                bw.write(line);
                bw.newLine();
                bw.flush();
            }
        }

        //释放资源
        sgs.close();
    }
}

• 服务器:接收数据后写入文本文件中
  ServerDemo类

package Demo;


import java.io.*;
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 sk = new ServerSocket(1110);

        //侦听此客户端套接字并建立连接
        Socket sgs = sk.accept();

        //获取输入流,读数据,并写入文本文件中
        BufferedReader br = new BufferedReader(new InputStreamReader(sgs.getInputStream()));

        BufferedWriter bw = new BufferedWriter(new FileWriter("c:\Lianxi\java.txt"));
        String line;
        while((line=br.readLine())!=null) {
            bw.write(line);
            bw.newLine();
            bw.flush();
        }

        //释放资源
        sk.close();
    }
}
