Doubt K&B chapter 1 javabean names

K & B says on page 9 (talking about JavaBeans):

"Listener methond names used to "register" a listener with an event source must use the prefix , followed by the listener type."

In the self test, question 5, one of the choices for a method name following the JavaBeans standard is . The answer key says this does not follow the standard. I still don't see why. Granted "size" is an absolutely terrible name for a listener, but if you did name your listener that, wouldn't it still work? Or does "standard" in "JavaBeans standard" imply that you will choose sensible names for your variables?

Thanks,

Josh

In that thread, you seem to be implying that whether "add" is correct or not depends on the purpose of the method. But the question in K & B says nothing about the method purpose.

To put it another way, if my method purpose is to add a listener named "size", then "addSize" is correct.

Let me know if I'm still missing something.

BTW, I'm electing to continue the discussion here rather than the old thread since this thread title conforms to the "doubt" standards recently defined in the errata thread.

Here is another thread about this.

Hey Josh -

Thanks for creeating such a well named thread

So, in our errata, we've mentioned that we're going to enhance page 9 to say that by convention Listeners have to end with the word "Listener". We're hoping that that covers it...what do you guys think?
