Evaluating Checkbox Boolean Value

Question

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!

Answer 1

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)

Answer 2

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);
}

Answer 3

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() .
