如何利用Java制作起始页面计数器

   /*qywjs.java*/
  import java.awt.*;
  import java.net.*;
  import java.io.*;
  public class qywjs extends java.applet.Applet
   {
    Font fn=new Font("TimesRoman",Font.BOLD,14);
    /*设置显示字体及大小*/
    String count_str;  /*存计数器的值*/
    public void init() /*初始*/
    {
      try
      {
        URL bookURL=new  URL
("
@h:\\www\\qywjs\\qywjs.PRG");  /*调入CGI程序*/
        DataInputStream book_is;
book_is=new DataInputStream(bookURL.openStream());
count_str=book_is.readLine(); /*读入计数值*/
  book_is.close();
        repaint();
      }
catch (MalformedURLException mfURLe)
{System.out.println("MalformedURLException:"+mfURLe);}
catch (IOException ioe)
{System.out.println("IOException:"+ioe);}
      }

    public void paint(Graphics g)  /*显示*/
    {g.setFont(fn);
     g.setColor(Color.blue);
     g.drawString("从2007年06月05日开始，
    你是第 "+count_str+" 位用户光临!",16,16);
    }
  }
