**JAVA PROGRAMMING**

I created this with JavaFX in Eclipse. I am trying to make this invoice input a date in the textField_date when the total button is clicked. I would like to create a GetTax in the Parent Class. Before I started trying to put the date information in this everything else works properly. I cant figure out how to do this. I would also like to see a UML for this program, I built it but now I am confused. Thanks! I appreciate all the help I have received so far, I need to get this finished as soon as possible.
