Since this is cross-posted to comp.lang.java.programmer and
comp.lang.c, let me clarify that point.
C defines an "object" as a "region of data storage in the execution
environment, the contents of which can represent values". This has
nothing to do with object-oriented programming. Thus a declared
variable of type int certain is an "object" if you use the C
definition of the term. (Note that C++ uses a very similar
definition.)
I don't know how "Java" defines the term.
That may be, but the context to which Arne replied and that you excised
claimed that Java has tons of memory overhead to represent an 'int' by virtue
of being an object, which is a bloody falsehood. Clearly that poster was
using "object" in the current conventional computer-programming sense of the
word, and not in your more specialized frame.
FYI, and it absolutely freaking *ASTOUNDS* me that anyone presuming to call
themselves a programmer today has not gotten familiar with object-oriented
programming at least enough to know what an object is, I mean, come on,
already! - an object in Java is exactly what it is in any object-oriented
programming environment. Roughly it's a struct with built-in functions.
You really should expand your study. Start with the Wikipedia definition,
perhaps read Grady Booch. Being a C programmer is not a good excuse. In
fact, it's no excuse at all.
