            System.exit(0); // program end
 
    }   
 
}

my out put has a cancel button .. why do I need to have other one ?? I read this is the inter net and I did the same but I feel I am missing my program up

That code doesn't look as though it would compile - does it? There's no ; after showMessageDialog, and no closing curly bracket on the actionPerformed method. If your code doesn't compile, copy and paste the compiler output.

Just to let you know, you're adding a button to a JPanel, then a JPanel to a button. Let me know how that works out!

You also don't seem to have a Frame of any sort as far as I can tell. You're basically adding theoretical objects to more theoretical objects. Nothing will ever appear on screen.

And Sean4u is right... this code probably won't compile.
