Temel olarak bir istemci-sunucu çok oyunculu oyun yazıyor. Bir RequestForGame alırsa bir gameThread oluşturan bir SeverCommunicationThread var bir gameThread oluşturur. Bir RequestForGame istisnası gönderdiğimde java.io.StreamCorruptedException istisnası atılır: geçersiz tür kodu: 00 Her iki iş parçacığının aynı ObjectInputStream okumayı denediğinden dolayı, bunun nasıl çalıştığına dair pek bir fikrim yok, sadece nasıl olduğunu biliyorum onu kullanmak için. Sorunun ne olduğunu ve nasıl düzeltileceğini anlamama yardımcı olabilir misiniz? Teşekkür :)java.io.StreamCorruptedException: geçersiz tür kodu: 00

i sorunu sanmıyorum gerçi model.addClient yöntemi burada
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
e.printStackTrace();
}
}
}

ServerModelManager, 'model.addClient (rumuz, bağlantıSocket, outToClient, inFromClient) 'i çağırdığınızda ne yapıyor? İçinde akışı bozan bir kod olabilir. – Vulcan
addClient (kullanıcıyı, soket, objektekutusu ve girdi akışını tutan ClientRepresantative bir ArrayList'e ekler.) Hiçbir şey okumadı – user1420273
Tamam. Ayrıca, üstbilginin gönderilmesini sağlamak için bunları oluşturduktan sonra ObjectOutputStreams öğesini temizlemelisiniz. Bu hatayı almanızın nedeni olabilir; Akış başlığı henüz geçmedi. ObjectOutputStream'i, oluşturulduktan sonra hem istemcide hem de sunucuda yıkayın. – Vulcan
