Question

Using NetBeans IDE, write a JavaFX application that allows the user to choose insurance options. Use a ToggleGroup to allow the user to select only one of two insurance types—HMO (health maintenance organization) or PPO (preferred provider organization). Use CheckBoxes for dental insurance and vision insurance options; the user can select one option, both options, or neither option. As the user selects each option, display its name and price in a text field; the HMO costs $200 per month, the PPO costs $600 per month, the dental coverage adds $75 per month, and the vision care adds $20 per month. Save the project as FXInsurance.
