Java. Show competent object transfer from client to server

I want to transfer an object from a client to a server, I found a bunch of examples, I realized that I needed an object stream and what method to call.

SERVER

startB.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { thread = new Thread(new Runnable() { public void run() { try { int i = 0; // счётчик подключений server = new ServerSocket(6666, 0, InetAddress.getByName("localhost")); System.out.println("server is started"); // слушаем порт while (true) { // ждём нового подключения, после чего запускаем обработку клиента // в новый вычислительный поток и увеличиваем счётчик на единичку new NewConnection(i, server.accept()); i++; System.out.println(server.getInetAddress()); } } catch (Exception e) { } // вывод исключений } }); thread.setDaemon(true); thread.start(); } }); public class NewConnection extends Thread { ClientsMessage msg = null; Socket s; int num; NewConnection(int num, Socket s) { this.num = num; this.s = s; setDaemon(true); setPriority(NORM_PRIORITY); start(); System.out.println("Got client"); try { ServerProgram.inStr = s.getInputStream(); ServerProgram.inObject = new ObjectInputStream(ServerProgram.inStr); } catch (Exception e) { e.printStackTrace(); } } public void run() { while(true) { try{ msg = (ClientsMessage) ServerProgram.inObject.readObject(); System.out.println(msg.name + " " + msg.surname); } catch (Exception e) { e.printStackTrace(); } } }
