how to deselect radio button in java

To deselect a radio button in Java, you can use the setSelected(false) method of the JRadioButton class. This method sets the radio button's selection state to false, which means it will not be selected.

Here's an example of how to deselect a radio button:

JRadioButton radioButton = new JRadioButton("Option 1");

// Deselect the radio button
radioButton.setSelected(false);

If you want to deselect all radio buttons in a group, you can use the clearSelection() method of the ButtonGroup class. This method deselects all the buttons in the group.

Here's an example of how to deselect all radio buttons in a group:

ButtonGroup group = new ButtonGroup();

JRadioButton radioButton1 = new JRadioButton("Option 1");
JRadioButton radioButton2 = new JRadioButton("Option 2");
JRadioButton radioButton3 = new JRadioButton("Option 3");

// Add the radio buttons to the group
group.add(radioButton1);
group.add(radioButton2);
group.add(radioButton3);

// Deselect all radio buttons in the group
group.clearSelection();

Note that the clearSelection() method does not remove the radio buttons from the group. It only deselects them. To remove a radio button from a group, you can use the remove(AbstractButton b) method of the ButtonGroup class and pass it the radio button you want to remove.
