Server

package socket;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.PrintWriter;

import java.net.ServerSocket;

public class TCPServer {

//1、创建一个服务器端的Socket，即ServerSocket，指定绑定的端口，并对其监听

ServerSocket socket = new ServerSocket(5000);

//2、调用accept()方法对其监听，并等待客户端的响应

System.out.println("****服务器即将启动，等待客户端的连接****");

Socket socket2 = socket.accept();//在没有连接前，处于阻塞状态

//3、获取输入流，并等待客户端的响应

InputStream iStream = socket2.getInputStream();

BufferedReader bReader = new BufferedReader(iReader);//缓存存储

String info = null;

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

}

socket2.shutdownInput();

//4、获取输出流，响应客户端的响应

PrintWriter pWriter = new PrintWriter(oStream);

pWriter.write("欢迎你登入!!!");

pWriter.flush();

//5、关闭资源

oStream.close();

pWriter.close();

bReader.close();

iStream.close();

socket.close();

} catch (IOException e) {

}

Client

package socket;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.PrintWriter;

import java.net.Socket;

import java.net.UnknownHostException;

/*

 * 基于TCP协议的客户端

 */

public class TCPClient {

public static void main(String[] args) {

try {

//1、创建客户端的Socket，并指定地址和端口

Socket socket = new Socket("localhost", 5000);

//2、获取输出流，向服务器发送信息

OutputStream oStream = socket.getOutputStream();//字节输出流

PrintWriter pWriter = new PrintWriter(oStream);//将输出流转换成打印流

pWriter.write("用户名：admin；密码：123");

pWriter.flush();

socket.shutdownInput();

//3、接收服务器发送来的反馈信息

InputStream iStream = socket.getInputStream();

//InputStreamReader inputStreamReader = new InputStreamReader(iStream);//将字节流转换成字符流

BufferedReader bReader = new BufferedReader(new InputStreamReader(iStream));

String info = null;

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

System.out.println("我是客户端，服务器反馈的信息："+info);

}

//4、关闭资源

iStream.close();

bReader.close();

pWriter.close();

oStream.close();

socket.close();

} catch (UnknownHostException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

}

按照视频讲的代码来写的，Server可以正常运行，但运行Client就会报这个错误

有没有知道怎么回事
