How do you update JLabels within a clicking game? - jlabel

Question

I'm in a Programming and Problem Solving 1 class and this lab that we have is giving me a bit of trouble. Our professor has written out the bare bones code for the game "Cookie Clicker" and has asked us to fill in the rest to make the game actually work (if you aren't already familiar with the game, you most likely will not be able to help). As of now, the game has all the buttons already but if you click any of them, nothing happens. If anybody could show me how to update the JLabels so that the buttons show the correct numbers each time they're clicked, it'd be greatly appreciated. The part that needs the code is marked by //Start and //End, almost all the way at the bottom.
