RE: Learning java - any advice please?

Agreed...  The ideas of OO can be a bit arcane... I think we both agree that 
once you understand the concepts of
inheritance, polymorphism, and encapsulation you should start coding...

I still laugh at some of my early attempts at OOP... heck, I laugh at stuff I 
did last week!!!!

This is good advise for all but  the "learning object-orientation" part of
Java.  A few things really do need to be learned in some kind of formal
setting.  A good class or, failing that, a good book is mandetory for this
one.  It's not as hard as calculus, but it is nontrivial enough that you
really want to learn it from a good practitioner -- nothing will save you
more time and grief.

Getting started "procedurally" is OK because you really have no practical
choice.  But, make a commitment to learn object-orientation in some kind of
formal manner.  It's half the point of Java and it can really pay off big
to you and your business.
