How to do something if checkbox is selected?

Question

I have a swing GUI, I'm trying to get my GUI to close if a certain requirement is met only if the checkbox is checked JCheckBox C1 = new JCheckBox("checkbox 1"); so the code should be something like if(Jcheckbox is pressed) //do something

if that makes sense

There are decent tutorials for this: [JCheckBox and JButton Tutorial](https://docs.oracle.com/javase/tutorial/uiswing/components/button.html) — Hovercraft Full Of Eels, Mar 22 '20 at 15:34

Try this:

if(c1.isSelected()){
    // your code
}

or use event if you want to do some action when the selection happens

myCheckBox.addItemListener((ItemEvent e) {
        if(e.getStateChange() == ItemEvent.SELECTED) {
            //do something...
        } else {//checkbox has been deselected
            //do something...
        }
    }
});
