I just created a simple JFrame window using the Netbeans graphic editor. In another file (mazesolver.java), I have a program where the computer solves a labyrinth (read a matrix). The idea would be, that instead of seeing the progress in the console, I could see it in the JFrame window mentioned above. What happens is that I do not know how to "send" data from one file to another, like referring to something from the JFrame from the mazasolver.java file.
If you could give me some guidance, I would be grateful.
