TCP通信程序的练习4

• 客户端:数据来自文本文件
  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 FileReader("C:\LianXi\java1.txt"));

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

        String line;
        while((line= br.readLine())!=null){
                bw.write(line);
                bw.newLine();
                bw.flush();
            
        }

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

• 服务器:接收的数据写入文本文件
  ServerDemo

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\javaCopy.txt"));
        String line;
        while((line=br.readLine())!=null) {
            bw.write(line);
            bw.newLine();
            bw.flush();
        }

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