java.net.SocketException: Broken pipe (Write failed)发生原因及其解决办法

先运行B.main,再运行A.main,先运行B的main，然后由于B有accepte的执行，所以B那块先阻塞，然后点击执行A.main的时候会执行A的socket连接，然后B监听到了之后立即写入，此时A和B是两个进程再运行，所以如果A先把Socket关闭时，B再通过Socket写入数据就会导致$java.net.SocketException:Brokenpipe(Writefailed)$，解决办法就是防止一端关闭Socket后另外一端仍然通过Socket写入数据！！！！

import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class Main {
    public static void main(String[] args) {

    }
}
class A extends  Thread{
    Socket s ;

    /**

     * @throws ClassNotFoundException
     */
    public A() throws IOException ,ClassNotFoundException{
        s=new Socket("127.0.0.1", 9999);
        s.close();
    }

    @Override
    public void run() {
        try
        {
            ObjectInputStream ois = new ObjectInputStream(s.getInputStream());
            Integer i = (Integer)ois.readObject();
            System.out.println(i);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

    }

    public static void main(String[] args)throws IOException,ClassNotFoundException {
        new A().start();
    }
}
class B extends Thread{
    ServerSocket ss ;
    Socket s ;

    /**
     * 服务器
     * @throws IOException
     */
    B()throws IOException{
        ss = new ServerSocket(9999);


    }
    @Override
    public void run() {
        try
        {
            s = ss.accept();
            System.out.println("Receive Successfully!!");
            Integer i = new Integer(1);
            ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream());
            oos.writeObject(i);
        }
        catch(IOException e)
        {
            e.printStackTrace();
        }

    }

    public static void main(String[] args) throws IOException,ClassNotFoundException{
        new B().start();
    }
}
