server.java

这个程序实现的是TCP协议和UDP

package org.hwl.tcp;
import java.net.*;
import java.io.*;
public class Server {
   private java.net.ServerSocket server;
   
   public Server()
   {
	   try{
	      server=new ServerSocket(9009); 
	      while(true)
	      {
	    	 Socket socket;
	    	 socket=server.accept();
	    	 
	      }
	   
	   }catch(IOException ex)
	   {
		   ex.printStackTrace();
	   }finally{
		   if(server!=null)
			   try{
			   server.close();
			   }catch(IOException ex)
			   {
				   ex.printStackTrace();
			   }
	   }
   }
   class print extends Thread
   {
	   
   }
}
