JAVA_HA16.0: UI Controls Demo

JavaFX provides many UI controls for developing a comprehensive user interface. Write a program (UIControlsDemo.java) that uses a variety of JavaFX UI controls including button, checkbox, radio button, and text field. The code is combined and modified of the following source code files from the required textbook (Liang, 2015, 10th edition):

LISTING 16.2, ButtonDemo.java, pages 633-634

LISTING 16.3, CheckBoxDemo.java, pages 635-636

LISTING 16.4, RadioButton.java, pages 638-639

LISTING 16.5, TextFieldDemo.java, pages 639-640

Submit the source code file - UIControlsDemo.java - to the drop box HA16.0.
