Więc zasadniczo piszę grę wieloosobową klient-serwer. Mam SeverCommunicationThread, który tworzy gameThread, jeśli otrzyma RequestForGame, tworzy gameThread. Gdy wysyłam wyjątek RequestForGame, zgłaszany jest java.io.StreamCorruptedException: niepoprawny kod typu: 00 Zakładam, że ponieważ oba wątki próbują odczytać ten sam obiekt ObjectInputStream, nie mam zbyt dużego zrozumienia, jak to działa, po prostu wiem, jak używać to. Czy możesz pomóc mi zrozumieć, jaki jest problem i jak to naprawić? Dzięki :)

metoda model.addClient, choć nie sądzę, aby problem był tutaj

  public void addClient(String nickname, Socket       clientSocket,ObjectOutputStream stream,ObjectInputStream inStream)
{
    clients.addClient(nickname, clientSocket,stream,inStream);//add to arraylist
//send client list to all clients
    String[] users=this.getAvailableClients();
    ObjectOutputStream[] streams=clients.getOutStreams();
    for(int i=0;i<streams.length;i++)
    {
        try {
            streams[i].writeObject(users);
        } catch (IOException e) {
            // TODO Auto-generated catch block
