我目前正在构建一些网络应用程序。其中一种方法ANDgate()使用套接字来传输一些字节。客户端

public static ArrayList ANDgate(ArrayList bits, ArrayList macs, ArrayList tags, int gateNumber) throws IOException, GeneralSecurityException, ClassNotFoundException
{
    Socket s= new Socket("192.168.1.109", 8888);
    ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream());
    ObjectInputStream ios = new ObjectInputStream(s.getInputStream());

    //Some computation

    oos.writeByte(p);
    oos.flush();
    oos.writeByte(p1);
    oos.flush();

    //Some computation        
    byte P = ios.readByte();
    byte P1 = ios.readByte();

    //Some computation
    oos.writeByte(p_shared1);
    oos.flush();

    //Some computation      
    byte p_shared2 = ios.readByte();

    //Some computation      
    oos.writeByte(p1_shared2);
    oos.flush();        
    //Some computation      
    oos.close();
    ios.close();
    s.close();

}

在服务器端，我有几乎相同的代码。运行程序时，该方法可以调用并成功执行1000次（或更多），但随机出现如下错误

Exception in thread "main" java.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)
at java.io.ObjectInputStream.<init>(Unknown Source)
at Gate.ANDgate(Gate.java:119)

119线是这个ObjectInputStream ios = new ObjectInputStream(s.getInputStream());

预先感谢您的帮助
