JavaFX RadioButton
Creating a RadioButton

Reading Selected State
ToggleGroup

A JavaFX RadioButton is a button that can be selected or not selected. The RadioButton is very similar to the JavaFX ToggleButton, but with the difference that a RadioButton cannot be "unselected" once selected. If RadioButtons are part of a ToggleGroup then once a RadioButton has been selected for the first time, there must be one RadioButton selected in the ToggleGroup .

The JavaFX RadioButton is represented by the class javafx.scene.control.RadioButton. The RadioButton class is a subclass of the ToggleButton class.
