How to actualize JProgressBar in Swing application?

In my school project (simple Swing application) I have a class that does some computational stuff (trains neural network) and this computation runs in iterations. I would like to actualize some GUI components (JProgressBar) and show to the user what iteration is actually processed (e.g. 100/10000).

I would like to ask how to accomplish it with respect to application design. I don't want to mix computation code with code for refreshing GUI components. Is it a proper situation to use Observer design pattern? If so, I can set my computation class as an observable object and register observer - class that will actualize JProgressBar.

Is it ok or is there some better way how to achieve it?

Depending on how much time your computation takes, you should also consider SwingWorker. Also having observer or some kind of handler which will update gui is good idea.
