本文介绍了一个使用Java进行网络文件传输的实例，包括客户端和服务端的实现。客户端从本地读取图片文件并发送到指定的服务器地址，服务器接收文件并保存为副本，同时向客户端返回确认消息。

package sock;

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;

public class MySock5 {
    public static void main(String[] args) throws Exception {
        FileInputStream inputStream = new FileInputStream("d:/美女.jpg");
        byte[] arr = new byte[1234];
        int res = 0;
        Socket socket = new Socket("127.0.0.1", 12331);
        OutputStream out = socket.getOutputStream();

        while ((res = inputStream.read(arr)) != -1) {

            out.write(arr);
        }
        socket.shutdownOutput();
        InputStream in2 = socket.getInputStream();
        byte[] bytes = new byte[1234];
        int read = in2.read(bytes);
        System.out.println(new String(bytes,0,read,"utf-8"));
        inputStream.close();
        socket.close();


    }
