How to use JOptionPane after using removeTouching?

#
I'm coding for my end of the year project and I wasn't sure how to code this. So my game has the player move around and when he picks up an item (removeTouching), I want a confirm dialog to pop up and ask a trivia question that can be answered with a yes/no/cancel option. The code below is what I have so far however it does not work, no confrim dialog pops up like it should. Any help would be appreciated, thank you
?

It doesn't have a yes/no option, but in general, Greenfoot.ask() is easier than JOptionPane. In modern versions of Greenfoot there are issues to do with window ordering if you try to use dialogs in your code.
