CHECKBOXES

A checkbox is a small box that when clicked a check mark will appear within it. If clicked again, it will remove the check mark. By default a checkbox is always off, however it can be set to the “on” state. We can do this when we initialize the checkbox and specify that it is true, meaning it is on.
Checkbox box1 = new checkbox(“ON”, true);

The label of the checkbox is passed as an argument.
Checkbox groups are often referred to as radio buttons. With radio buttons, only one button can be selected at a time. To create a checkbox group or radio buttons, a CheckboxGroup object needs to be created.
CheckboxGroup answer = new CheckboxGroup( );
To create a box from the group answer:
Checkbox sayyes = new Checkbox(“YES”, answer);
For all checkboxes, when it is clicked an item event occurs. There needs to be and ItemListenter from the listener class, that is attached to the event.
