我正在尝试开发一个非常简单的客户端/服务器,客户端将文件转换为字节,将其发送到服务器,然后将字节转换回文件.

目前该程序只是创建一个空文件.我不是一个出色的Java开发人员,所以任何帮助都非常感谢.

这是接收客户端发送内容的服务器部分.

ServerSocket serverSocket = null;

    serverSocket = new ServerSocket(4444);


    Socket socket = null;
    socket = serverSocket.accept();

    DataOutputStream out = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
    DataInputStream in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));
    byte[] bytes = new byte[1024];

    in.read(bytes);
    System.out.println(bytes);

    FileOutputStream fos = new FileOutputStream("C:\\test2.xml");
    fos.write(bytes);

这是客户端部分

Socket socket = null;
    DataOutputStream out = null;
    DataInputStream in = null;
    String host = "127.0.0.1";     

    socket = new Socket(host, 4444);
    out = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
    in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));

    File file = new File("C:\\test.xml"); …
