Fee Payment Module

Hi
After the last hello world program in javafx, I started developing an app to check for student fee payment details based on the bill number. Only the interface part is done.

In developing this interface, I have used BorderPane, StackPane, HBox, VBox, TextField, Label, and Button (to toggle fullscreen mode).

The interface displays the college name, department (in this case it is Academic Section), followed by date. There  is a text field that takes the bill number.
A Full screen button to toggle fullscreen.

Hope it is useful for your understanding of javafx.
