问如何用Java套接字实现文件传输？

EN

//Send file (Server)
//Put this in a thread
Socket socket = new Socket(destinationIP, destinationPort);
ObjectOutputStream sender = new ObjectOutputStream(socket.getOutputStream());
sender.writeObject(dataToSend);

//Receive File (Client)
//Kick off a new thread to receive the file to preserve the liveness of the program
ServerSocket serverSocket = new ServerSocket(ListenPort);
socket = new Socket();
while (true) {
        new Thread(new TCPReceiver(socket)).start();
}

//Receive file thread TCPReceiver(Socket socket)
//Get the stream where the object is to be sent
ObjectInputStream objectInputStream = new ObjectInputStream(socket.getInputStream());

/*  Where type is the type of data you send... String or anything really...
    read part of the file into something and send it then at this end use the same data                                                       
    type to recieve it and it will magically pull the entire object across.

while(fileIsIncomplete){
    type recievedData = (type) objectInputStream.readObject();
    //Reconstruct file
}
