Thank you, Laird.
So what's that implementation other than Sun's?
Can I use it to control the order that EventListener get called?

Well, if you were using, say, the IBM VM or something like that, then
they are free to fire events to listeners in any order they wish.

No.  I mean, yes, you can figure out how any given Java platform
implementor (Sun, IBM, whoever...) does it by looking in their source
code, but the specification says no, you can't count on listeners
being fired in any particular order.

Best,
Laird

All right, I understand now.
Looks like a bad idea to register multiple listeners in my example
because, that "value" obtained by the calculator can be different
depending on which listener execute first.
