Hi ted,
I am a newbie like you so I can't explain the difference between your
book and what you got but i can advice you to read the PDF book
provided by Apple : Java For WO Developper, you will learn a lot on
Java, specially the mustknown to write and understand code in WO.
You can download this book here in the Download section of the ADC
member site. The book is in the PDF compilation of the all the
developper doc, provided as a .dmg file
As for the difference between protected and public :
theses keywords are "Access modifiers" and their role is to enforce
encapsulation. The public keyword allow any class to have acces to
your method or instance or class variables meanwhile the protected
keyword allow only subclasses to have access to them.
Hope it will help you.
Gilles.
