JToggleButton – Java Swing – Example

In this tutorial, we are going to see an example of JToggleButton in Java Swing. JToggleButton is a button with two states (selected and deselected). JRadioButton and JCheckBox classes are subclasses of this class. When the user presses the toggle button, it switches between clicked and unclicked. JToggleButton is used to select a choice from a list of possible choices. Buttons can be configured and controlled by actions. Using an action with a button has many advantages beyond the direct configuration of a button.
