John, I think that you can take your example of using named constants in C
and note that not only can you abstract constant data names in java, but
also types and methods.
So if you have a musical instrument class with methods play() and data for
pitch range and key, you can define subclasses for class flute, class oboh,
class cello, etc. All of these will define method play(). But you don't
need to know the type of an instrument at compile time -- just build an
orchestra as a list of instruments, and then for all the collection you play
whatever musical parts are required for that instrument.
Hope this clarifies -- this makes it possible to define libraries that can
be linked to the application and run without requiring much information
about the internals of the library.
This type of thing harks back to my C++ days. I think Java is not C on
steroids, but is better described as a subset of C++ on steroids. But
that's not altogether true also as the semantic and scope rules are slightly
different.
Java is its own language. I'm liking it more every day.
Now if I can get eclipse to work...

There are many discussions of this issue, and in fact entire books have been
published on the subject.
What exactly are you looking for? Design patterns, coding practices,
continuous integration methodologies, software engineering
paradigms?
Take care,
Sina

Subject: [brailleblaster] Writing extensible Java code
The discussion of using BrailleBlaster on various device has set me
wondering which Java coding practices lead to extensibiloity. In
C, one of them is to avoid hard-coding connstants into executable
statements.
I like to think of Java as C on steroids.
