I quickly explain what I intend, I have two runners running threads simulating running (sum of random value), it is a thread that executes and must for each iteration of the loop in the thread make a setvalue (distance run-time) in progressbar of the interface.
I think my problem is that it does not refresh the jframe and the changes are not seen at 2 progressbar
