java中的网络编程，在使用IO流时有问题

Question

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.ServerSocket;

import java.net.Socket;

public class Server {

public static void main(String[] args){

try {

ServerSocket ss=new ServerSocket(8888);

System.out.println("Reading:");

Socket s=ss.accept();

InputStream is=s.getInputStream();

InputStreamReader isr=new InputStreamReader(is);

BufferedReader br=new BufferedReader(isr);

String info=null;

while((info=br.readLine())!=null){

System.out.println("i am :"+info);

}

s.shutdownInput();

br.close();

isr.close();

is.close();

s.close();

ss.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

------------------------------------------------------------------------------

import java.io.IOException;

import java.io.OutputStream;

import java.io.PrintWriter;

import java.net.Socket;

import java.net.UnknownHostException;

public class client{

public static void main(String args[]){

try {

Socket s=new Socket("localhost",8888);

OutputStream os=s.getOutputStream();

PrintWriter pw=new PrintWriter(os);

pw.write("ddfdsaf");

pw.flush();

s.shutdownOutput();

pw.close();

os.close();

s.close();

} catch (UnknownHostException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

connection reset一般是由于你的SOCKET的关闭了
