Sybex 829 - Errata - CH7 - page 379: Note section setNumberEggs

[Koen Weterings]

The Note section in chapter 7 on page 379 refers to "the negative check we did with setNumberEggs()".
The negative check probably referred to was however inside the constructor of the "Crane" class on page 374 which was immutable and therefore didn't contain any setters.

The only usage of "setNumberEggs" I found within the kindle version of the book is in chapter 11 on page 604 as part of the IllegalArgumentException section. This is of course multiple chapters after the appearance of the mentioned note section and "we did" in this context doesn't seem to refer to that method.

Welcome to the Ranch That does sound like an error or at least confusion to me.

Hi Campbell Ritchie,

Thanks for welcoming me to the Ranch, seems very nice here.

Should I do anything else with this / report it somewhere else or is this the correct place for that?

If you need more information regarding this finding please let me know.

Have a nice day :-)

No. Please wait for Jeanne and Scott to read the post and they will ask for whatever they need.

Good eye. I've added this to the errata and credited you. I also gave you a cow here at the Ranch.

The correction is "You might think that you need custom checks for every field in the record, like for numberEggs". At one point we had a method there and then simplified it before publishing. We did not notice the note referred to the original, unpublished code.
