Hi Dean,
While we appreciate the errata you reporting, this is general
Java certification forum, and not all people have the book. To add more value to your post, could you share for example your scenario -- source
.java code and small demo how you run it from command line.
I am pretty sure many readers would appreciate these details. My guess is that the "user defined classes" must reside in the same source (either peer level or inner classes), no classes from user defined modules. Can we discuss in that direction?
Cheers,
MZ
