Chapter 12, Problem 3FTE
Explanation of Solution
Given program:
RadioButton radio1 = new RadioButton("Option 1"); //Line 1
RadioButton radio2 = new RadioButton("Option 2"); //Line 2
ToggleGroup radioGroup = new ToggleGroup(); //Line 3
radioGroup.setToggleGroup(radio1); //Line 4
radioGroup.setToggleGroup(radio2); //Line 5
RadioButton:
- User create a “RadioButton” control using the “RadioButton” class.
- This class is present in the package of “javafx.scene.control”.
- The controls “RadioButton” is used to permit the user to choose one option from the several possible options.
- It may be selected or deselected.
- Each “RadioButton” consist of a small circle.
- If a circle appears filled-in, then the “RadioButton” is selected.
- If a circle appears empty, then the “RadioButton” is deselected.
Example:
The example for “RadioButton” is shown below:
//create the radio button
RadioButton exampleButton = new RadioButton("Option 1");
ToggleGroup:
- It is one class of JavaFX application which is used to create toggle group.
- It is available in package “javafx.scene.control”.
- Generally, the “RadioButton” controls are grouped together in a toggle group.
- In a toggle group, only one of the “RadioButton” controls may be chosen at any time.
- Then this “RadioButton” are referred as “mutually exclusive”.
Example:
The example for “ToggleGroup” is shown below:
// create a ToggleGroup.
ToggleGroup newToggleGroup = new ToggleGroup();
- The above code is used to create a “ToggleGroup”.
Calling “RadioButton” in “ToggleGroup”:
The example for calling “RadioButton” in “ToggleGroup” is shown below:

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 TextField; 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.
Dice Simulator Create an application that simulates rolling a pair of dice. When the user clicks a button, the application should generate two random numbers, each in the range of 1 through 6, to represent the value of the dice. Use PictureBox controls to display the dice. (In the Student Sample Programs, in the Chap05 folder, you will find six images named Die1.bmp, Die2.bmp, Die3.bmp, Die4.bmp, Die5.bmp, and Die6.bmp that you can use in the PictureBoxes.)
