本文介绍了一个简单的TCP服务器和客户端实现方式。服务器监听8888端口接收客户端发送的HTTP请求，并返回HTML响应。客户端则通过Socket连接向服务器发送HTTP GET请求并打印服务器返回的内容。

服务器端 
package com.tcp;

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class Browser
{
	public static void main(String[] args)
	{
		try
		{
			ServerSocket ss=new ServerSocket(8888);
			System.out.println("服务器在 8888 监听。。。");
			while(true)
			{
				Socket socket=ss.accept();
				InputStream is=socket.getInputStream();
				byte[] b=new byte[1024];
				int l=is.read(b);
				String message=new String(b,0,l);
				System.out.println(message);
				
				PrintWriter pw=new PrintWriter(socket.getOutputStream(),true);
				pw.println("<h1>hello</h1>");
				
			}
			
	
		} catch (IOException e)
		{
			e.printStackTrace();
		}
	}
}





客户端 
package com.tcp;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;

public class IE
{
	public static void main(String[] args) throws Exception
	{
			Socket socket=new Socket("localhost",8888);
			PrintWriter pw=new PrintWriter(socket.getOutputStream(),true);
			pw.println("GET /1.html  / HTTP/1.1");
			pw.println("Accept: */*");
			pw.println("Host: localhost:8888");
			pw.println("Connection: Keep-Alive");
			pw.println("");
			
			
			BufferedReader br=new BufferedReader(new InputStreamReader(socket.getInputStream()));
			String str=null;
			while((str=br.readLine())!=null)
			{
				System.out.println(str);
			}
			
			
	}
}
