Ex: Finishing the calculator - miguelneto1123/CES-22 GitHub Wiki

After handling the exceptions, the only thing left was to make the GUI. And it feels great! Just running the main() on the MainFrame class makes a simple, tidy calculator pop in the screen, with all the simple functionalities it has to be. Of course, it doesn't take care of float division (everything is done with integers), but it's pretty nice. I used Eclipse plug-in WindowBuilder to make things easier when putting the buttons. A video explaining and showing how it works (in Portuguese) can be found here.
