如何創建自動關閉系統的谷歌瀏覽器插件

我有一個用於自動關閉系統的java代碼。的代碼如下： -如何創建自動關閉系統的谷歌瀏覽器插件

import javax.swing.JOptionPane; 

public class sd 
{ 
    public static void main(String[]args) 
    { 
     int wholeTimeBeforeShutdown=0; 

     int hour=0; 
     int minute=0; 
     int second=0; 

     try 
     { 
      String a=JOptionPane.showInputDialog(null,"HOUR","HOUR BEFORE SHUTDOWN",JOptionPane.QUESTION_MESSAGE); 
      String b=JOptionPane.showInputDialog(null,"MINUTE","MINUTE BEFORE SHUTDOWN",JOptionPane.QUESTION_MESSAGE); 
      String c=JOptionPane.showInputDialog(null,"SECOND","SECOND BEFORE SHUTDOWN",JOptionPane.QUESTION_MESSAGE); 

      if((a==null)||a.equals("")) 
      { 
       a="0"; 
      } 
      if((b==null)||b.equals("")) 
      { 
       b="0"; 
      } 
      if((c==null)||c.equals("")) 
      { 
       c="0"; 
      } 

      int e=Integer.parseInt(a); 
      int f=Integer.parseInt(b); 
      int g=Integer.parseInt(c); 

      wholeTimeBeforeShutdown=wholeTimeBeforeShutdown+((e*60)*60); 
      wholeTimeBeforeShutdown=wholeTimeBeforeShutdown+((f*60)); 
      wholeTimeBeforeShutdown=wholeTimeBeforeShutdown+(g); 
      wholeTimeBeforeShutdown=wholeTimeBeforeShutdown*1000; 

      Thread.sleep(wholeTimeBeforeShutdown); 
      Runtime.getRuntime().exec("shutdown -s -t 00 -f"); 
     } 

      catch(Exception exception) 
      { 
       exception.printStackTrace(); 
      } 
    } 
}

我想利用這個代碼來創建谷歌瀏覽器時自動關閉系統中的插件。我知道如何在Chrome瀏覽器中添加一個插件，包括做各種編碼並將它們放在一個文件夾中並將該文件夾加載到Web瀏覽器中。我的問題是如何使用此代碼爲谷歌瀏覽器做一個「插件」？

爲什麼你需要關閉系統從Chrome？！？ – Hydroid 2013-04-06 12:30:17

我正在做一個關於chrome插件的項目，其中我應該使用插件關閉系統。 – 2013-04-06 12:38:06
