URL u4 = new URL(link4);
a4.showDocument(u4,"_self");
}
catch (MalformedURLException e)
{
System.out.println(e.getMessage());
}

}
}

Can you explain what the problem is? If you are getting errors, please post the full text of the error message.

Hi, simple error I spotted straight away is your class declaration:

public class Pritish extends Applet implements ActionListener implements Runnable
{
}

You have the implements keyword twice! To implement multiple interfaces, you just use the " , " character.

 public class Pritish extends Applet implements ActionListener,Runnable
 {
 }

Thanks all

But Akill,
i use netbeans and it shows me that
Pritish is a duplicate class
why so???
