我正在尝试实现一个小游戏，其中多个客户端必须连接到服务器并一起玩。每个人都有不同的 GUI，它们通过 ClientConnect 类进行通信，这是一个从 GUI 类开始的 Runnable。问题是我在第一行代码中得到了一个 EOFException，当我试图对输入流进行 intanciate 时。服务器当然是一开始就启动并发送一个对象。这是我得到异常的实现的一部分。
我应该怎么办？
public ClientConnect(InetAddress address, int port) throws IOException {
clientSock = new Socket(address, port);
}
@Override
public void run() {
ArrayList<Object> receivedObject = null;
try (ObjectInputStream fromServer = new ObjectInputStream(clientSock.getInputStream());
ObjectOutputStream toServer = new ObjectOutputStream(clientSock.getOutputStream()))
{
while(!move) {
receivedObject = (ArrayList<Object>) fromServer.readObject();
move = !(receivedObject.get(0).equals("you have to wait!!"));
}
actualPlayer = (String) receivedObject.get(0);
scoreCard = (List<String>) receivedObject.get(1);
highScore = (HashMap<String, Integer>) receivedObject.get(2);
numberOfPlayers = (int) receivedObject.get(3);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
这是一个例外：
CShellExt::CShelljava.io.EOFException
at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source)
at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source)
at java.io.ObjectInputStream.readStreamHeader(Unknown Source)

Ext()
第 41 行是带有 try 的行
我在 GUI 中启动 ClientConnect 线程，如下所示：
public void actionPerformed(ActionEvent arg0) {
//Online-Spiel starten
if(game.listLength()>0){
try {
client = new ClientConnect(InetAddress.getByName(null), 2000);
new Thread(client).start();
while (!client.getMove()) {
lblActualUser.setText("WAITING.... " + client.getActualPlayer() + " ist an der Reihe");
}
