Hi Laura and others,
Thanks for your patience. I think some of this just sunk in.
I will try to summarize in another message and see if it really did. It's going
to take me some time to write it.

Sorry Jim. Didn't mean to sound obfuscated. Taking one item from my
verbage and actually writing out the implementation may help.
You have java's class Int, which is a wrapper class for little int.
Now what this means is that somewhere in the implementation of Int, you have
a data member "ival", with integer value (that is, ival has type little
int).
Now there is no reason to assume anything else about this class, except that
it may have methods and additional data to do some fancy operations.
So suppose
Int Int::add(Int)
is a method that adds this.ival and arg.ival and updates this.ival if there
is no overflow.
The implementation might look like:
Int Int::addTo(Int arg)
{
// check for possible overflow, which
// can be done several ways ...
if ( !overflow )
this.ival += arg.ival;
return this;
}
Hope that makes sense.
Happy hacking.

Hi Laura,
Here's what I understood about your explanation. Bla, bla, bla, Java. Bla,
Bla, Bla, Jim. Bla, bla, bla, wrapper. Bla, bla, bla, capital. Bla, bla,
bla, operate.
I think I'm going down to the lobby for some of that fancy coffee. Maybe it
will operate on my brain and wrap it around some of this stuff you poor
people are patient enough to try to explain to me. Get it? wrap? Speaking of
wrap, that's not real music.
Speaking of music, can you make a beetle object and override it so that it
becomes a car, or a bug? Is override the right term? I gotta get off this
floor for a few minutes. Hope these allergy pills start to work.

Sometimes I feel like Lucy, the days when I have a problem with some

Hey Jim --, that's a great attitude!
I just got around to reading this thread and thought I'd add additional
flights of fancy -- fancy code, you understand...*smile*
If you define capital Int as a wrapper for int, you can not only treat it
like a class but also add functionality or attributes -- for example, you
can explicitly check for overflow when you operate on the value, or if you
don't want to worry about low level details, you can define it to have an
indefinite number of bits -- it can keep on growing as the value gets
larger.
How you do this is an implementation detail.
Anyway, obviously java doesn't do this with Int, I'm just having some fun
speculating...*smile*
Happy hacking.

Hay Dave,
I'm sure that both you and I inherited all the good stuff from our parents

Hey Jim,
Yes; getting "stuff" is technically called inheritance in that case.
Other terms for it are subclassing, extending, implementing, etc
depending on the context. The jist is that you want to specialize
something generic to something more specific. I'm sure you'll go
through this in your book, so I'll stop here :).
As for object, every java class inherits either directly or indirectly
from object. Just like human inheritance (somewhat), those who
inherit also get the parent's methods, attributes, etc (some
exceptions apply).
Java does define a default constructor (if you don't define one
yourself or if you've not defined any other constructors).
