I may have misunderstood the question. I thought the OP didn't want to be able to press the button again, once it has been changed.

JButton b = myButton("X");
b.setEnabled(false);

Please don't do this:


catch (InputMismatchException e) { //this is the error we are catching
}

As you are not catching anything. At a minimum, do this:


catch (InputMismatchException e)...

I recommend you put in a print statement in your loop to print out the values of n, rev, and a to see what is happening.

I am unfamiliar with your classes but some of this looks strange.


public void phoneCall()

Gadget mobPhone = Devices.get(getDisplayNum());
