Question

首先请原谅我的坏语言。我正在用java编写服务器客户端应用程序，我正在尝试将一个对象发送到服务器但是我得到一个异常一切看起来都很好我不明白有人可以帮我吗？这是我的代码如果我做错了警告我

服务器;

FAR PTR

客户端

import java.io.IOException;
import java.io.ObjectInputStream;
import java.net.InetSocketAddress;
import java.nio.channels.ServerSocketChannel;
import java.nio.channels.SocketChannel;

/**

 */
public class Server {

/**
 * @param args
 * @throws IOException 
 * @throws ClassNotFoundException 
 */
public static void main(String[] args) throws IOException, ClassNotFoundException {
    Server server = new Server();
    server.ReceiveObject();
}

private SocketChannel socketChannel = null;

void ReceiveObject() throws IOException, ClassNotFoundException{
    System.out.println("Server Started");
    socketChannel = CreateSocketChannel();
    ObjectInputStream ois = new ObjectInputStream(socketChannel.socket().getInputStream());
    Person person = (Person) ois.readObject();
    System.out.println("Object : "+ person.toString());
    socketChannel.close();

}
private SocketChannel CreateSocketChannel() throws IOException{

    ServerSocketChannel serverSocketChannel = ServerSocketChannel.open();
    serverSocketChannel.socket().bind(new InetSocketAddress(9100));
    socketChannel = serverSocketChannel.accept();

    System.out.println("Connection Etablished : " + socketChannel.getRemoteAddress());
    return socketChannel;
}

}

异常

 import java.io.Serializable;

private int age;
private String name;
