以上源码都能完成相应功能！是基础编程者学习着的好资料！

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

class Client
{
	Socket socket;
	BufferedReader fromServer;
	PrintStream toServer;
	
	Client()
	{
		try
		{
			socket = new Socket("127.0.0.1",6000); //连接IP地址  :本地机127...
			fromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
			toServer = new PrintStream(socket.getOutputStream());
			
			toServer.println("Hello Server");
			
			System.out.println(fromServer.readLine());
		}
		catch(Exception e){System.out.println(e);}
	}
	
	public static void main(String s[])
	{
		new Client();
	}
}
