您可以使用Java API创建对象流并发送任何可序列化的对象。但您必须注意，这些内容不会通过网络进行加密：

在发送方方面：

CustomObject objectToSend=new CustomObject();
Socket s = new Socket("yourhostname", 1234);
ObjectOutputStream out = new ObjectOutputStream(s.getOutputStream());
out.writeObject(objectToSend);
out.flush();

在接收端：

ServerSocket server = new ServerSocket(1234);
Socket s = server.accept();
ObjectInputStream in = new ObjectInputStream(s.getInputStream());
CustomObject objectReceived = (CustomObject) in.readObject();
