博客展示了Java实现简单Socket通信的代码。包含客户端类TextClient，通过Socket连接指定IP和端口；还有服务端类TextServer，使用ServerSocket监听指定端口，体现了Java在网络通信方面的应用。

import java.io.;
import java.net.;

class TextClient
{
public static void main(String[] args) throws Exception
{
Socket s = new Socket(“192.168.1.254”,10006);

	BufferedReader bufr = 
		new BufferedReader(new FileReader("IPDemo.java"));



	PrintWriter out = new PrintWriter(s.getOutputStream(),true);


	String line = null;
	while((line=bufr.readLine())!=null)
	{
		out.println(line);
	}

	s.shutdownOutput();//关闭客户端的输出流。相当于给流中加入一个结束标记-1.

	
	BufferedReader bufIn = new BufferedReader(new InputStreamReader(s.getInputStream()));

	String str = bufIn.readLine();
	System.out.println(str);

	bufr.close();

	s.close();
}

}
class TextServer
{
public static void main(String[] args) throws Exception
{
ServerSocket ss = new ServerSocket(10006);

	Socket s = ss.accept();
	String ip = s.getInetAddress().getHostAddress();
	System.out.println(ip+"....connected");


	BufferedReader bufIn = new BufferedReader(new InputStreamReader(s.getInputStream()));

	PrintWriter out  = new PrintWriter(new FileWriter("server.txt"),true);

	String line = null;

	while((line=bufIn.readLine())!=null)
	{
		//if("over".equals(line))
			//break;
		out.println(line);
	}

	PrintWriter pw = new PrintWriter(s.getOutputStream(),true);
	pw.println("上传成功");


	out.close();
	s.close();
	ss.close();

}

}
