在java中通过套接字正确发送MP3和JPEG文件

import java.io.*;
import java.net.*;

public class FileSender {
    public static void main(String[] args) {
        String serverIP = "服务器IP地址";
        int serverPort = 12345;
        String filePath = "文件路径";

        try {
            // 创建套接字并连接服务器
            Socket socket = new Socket(serverIP, serverPort);

            // 读取文件为字节流
            File file = new File(filePath);
            FileInputStream fis = new FileInputStream(file);
            byte[] buffer = new byte[(int) file.length()];
            fis.read(buffer);
            fis.close();

            // 发送字节流数据
            OutputStream os = socket.getOutputStream();
            os.write(buffer);
            os.flush();

            // 关闭套接字
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
