    Are you asking about having a GUI display that changes with time?
    What have you tried?

    jcheckbox is true
    The JCheckBox class or its super class has a method that can be called to see how it is set.

    identify if the 2 jcheckbox is checked
    Each check box has a method that will say if it is checked. Use that method for the 2 check boxes.

    It doesn't matter how many checkboxes you have, each of them has the same method that can be used to see if it is checked.
