如何使用JAVA将照片从一台计算机发送到另一台计算机(非本地)

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.Socket;

public class Sender {
    public static void main(String[] args) throws IOException {
        // 设置目标计算机的IP地址和端口号
        String ipAddress = "目标计算机的IP地址";
        int port = 1234;

        // 读取待发送的照片文件
        File photo = new File("待发送的照片路径");

        // 建立Socket连接
        Socket socket = new Socket(ipAddress, port);

        // 创建输入流和输出流
        BufferedInputStream bis = new BufferedInputStream(new FileInputStream(photo));
        BufferedOutputStream bos = new BufferedOutputStream(socket.getOutputStream());

        // 发送文件名和文件内容
        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = bis.read(buffer)) != -1) {
            bos.write(buffer, 0, bytesRead);
        }

        // 关闭流和Socket连接
        bis.close();
        bos.flush();
        bos.close();
        socket.close();
    }
}

public class Receiver {
    public static void main(String[] args) throws IOException {

        int port = 1234;

        // 创建ServerSocket对象
        ServerSocket serverSocket = new ServerSocket(port);

        // 等待客户端连接
        Socket socket = serverSocket.accept();

        // 创建输入流和输出流
        BufferedInputStream bis = new BufferedInputStream(socket.getInputStream());
        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream("保存路径"));

        // 接收文件内容
