Lagging problem

Question

Hello everyone
I just have a quick question.
I made an application that displays an array of cards in a JFrame with three buttons under it. One button perfectly shuffles the deck(I won't get into what I mean by that unless someone is interested) the other randomly shuffles the deck and the third sets the deck back in its original order. Everything works fine except when i push the button that sets the deck, it lags for a good 10 seconds before it works. Anyone have any ideas to why?
Thanks in advance

Kieth,
Thanks for the reply and the how to ask questions page.
I posted the wrong code, thats why the putDeckInOrder method didnt exist

As for the images being too large and too many,  I'm not positive but i dont think thats the problem because when either shuffle button is pressed there is no lag. its only for the put deck in order button.
do you want the images of the cards? i dont know how i would send them.
