 public class CheckboxGroup extends Object implements Serializable TheCheckboxGroupclass is used to group together a set ofCheckboxbuttons.Exactly one check box button in a CheckboxGroupcan be in the "on" state at any given time. Pushing any button sets its state to "on" and forces any other button that is in the "on" state into the "off" state.The following code example produces a new check box group, with three check boxes: setLayout(new GridLayout(3, 1)); CheckboxGroup cbg = new CheckboxGroup(); add(new Checkbox("one", cbg, true)); add(new Checkbox("two", cbg, false)); add(new Checkbox("three", cbg, false));
