swing - Class Structure and Location for MVC in Java -

I am writing a GUI for the Sudoku program. I am trying to use an MVC framework, the following post was the basis of the basis of my current code: My question is where do the action listeners go? I think they go to the controller, but is that one class or many? Currently I have a single class with a single action listener and if there is any other argument to deal with each swing component which can fire an event. This code smells for me though. Is there a preferred way to structure code? I hope some more buttons and components have to be added and I want to make sure that I am doing it down properly. I've read a lot of posts and web tutorials, but have received this answer so far.

Thanks

 I got was very helpful. controller view and add-Listnr method Basically the internal classes of issues. In this way better organization
