以下是代码

服务器：

package com.zhang;

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;

import java.net.Socket;

public class InetAddress1 {

public static void main(String[] args){

try {

ServerSocket serverSocket=new ServerSocket(8888);

System.out.println("****服务器即将启动****");

Socket sc=serverSocket.accept();

InputStream is=sc.getInputStream();

InputStreamReader isr=new InputStreamReader(is);

BufferedReader br=new BufferedReader(isr);

String in="";

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

System.out.println("服务器：客户端发来的信息是"+in);

}

System.out.println("111");

sc.shutdownInput();

OutputStream os=sc.getOutputStream();

PrintWriter pw=new PrintWriter(os);

pw.write("欢迎光临！");

pw.flush();

os.close();

pw.close();

is.close();

isr.close();

br.close();

sc.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

客户端：

package com.zhang;

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;

public class client {

/**

*/

public static void main(String[] args) {

try {

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

OutputStream os=socket.getOutputStream();

PrintWriter pw=new PrintWriter(os);

pw.write("账户：zxcv200cool  密码：zxcvbnm2008");

pw.flush();

System.out.println("数据发送成功");

InputStream is1=socket.getInputStream();

InputStreamReader isr1=new InputStreamReader(is1);

BufferedReader br1=new BufferedReader(isr1);

String next=null;

while((next=br1.readLine())!=null){

System.out.println("客户端：服务器发来的信息是"+next);

}

is1.close();

isr1.close();

br1.close();

socket.close();

os.close();

pw.close();

} catch (UnknownHostException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}
