1. What do you need to submit? (minimal submitted files) You are required, but not limited, to turn in the following source files: Assignment6.java (Download this file and use it as your driver program for this assignment. This class is complete. You do not need to add code to this class) GeneratePane.java (Download this file. You need to add more code to complete it.) SelectPane.java (Download this file. You need to add more code to complete it.) Department.java (Download this file- this is complete) 2. Requirements to get full credits in Documentation 1. The assignment number, your name, StudentID, Lecture time, and a class description need to be included at the top of each class/file. 2. A description of each method is also needed. 3. Some additional comments inside of methods to explain code that are hard to follow 3. New Skills to be Applied JavaFX (Check here for JavaFX API https://docs.oracle.com/javase/8/javafx/api/e ) (Note: for this GUI application, you cannot use Swing/AWT package, you must implement it by using JavaFX, using Swing/AWT package will result a "O" grade!) In addition to what has been covered in previous assignments, the use of the following items, discussed in class, will probably be needed: JavaFX, ArrayList Classes may be needed: Button, TextField, TextArea, Label, CheckButton, and ActionHandler. You may use other classes. 4.
