Evaluating Checkbox Boolean Value

I'm sure this is a rediculously easy question, but I just can't find the answer to it anywhere. I have a JCheckbox that I need to evaluate the boolean value of, and then change the value with an if statement. The problem is I just can't find the syntax anywhere for evaluating the contents of a JCheckbox, let alone changing it. This will probably be really easy one, but I just can't seem to find anything helpful. Thanks!

There is an awesome tutorial from Sun that you can read to complete your knowledge. If you want to know the current selection state of a JCheckbox, just use the method isSelected().

Do you mean how to check if Checkbox is selected or not, if yes then use isSelected

boolean isSelected = jCheckBox.isSelected();

if(isSelected ){
   jCheckBox.setSelected(false);
} else {
   jCheckBox.setSelected(true);
}

This SO thread sort of answers your question. If your JCheckBox is named "Foo", you would check its value with

Foo.isSelected()

To set its value, you would use

Foo.setSelected(true)
