Java Please add comments so I follow and understand. Thanks

Create a graphical user interface for it using JavaFX. In addition to the native JavaFX, also use Controls- FX (http://fxexperience.com/controlsfx/). The user should start the program and be able to open a file using a file selector. The file should be presented in the user interface in one text field and the errors in another. Use ControlsFX to make your application better, we like you to experiment with it and use the controls you see fit to make your application better or nicer to look at.
