Heh. Okay, that makes sense now.
Of course, the answer is the same. java.sun.com Smile

Internet etiquette specifies message signatures to be no longer than 3
lines. Please refrain from posting messages with signatures longer
than 3 lines so they doesn't waste my 6Mbps bandwidth.

Excuse my naive question, but do these 3 more lines with (max) 80 signs
(=240 bytes!) really make a difference?

It's not the bandwidth usage that is the problem. For some people, they
have a 6+ line sig and their message may be 2 lines long. It just
doesn't make sense to have a signature longer than your message.

With all the complaining Andrew does concerning people's grammar,
spelling, punctuation, etc. you would think he would fix his own
signature before complaining about someone else.

Do you have any references/links for that ?

Unfortunately, no. About 15 years ago, I used a C++ compiler for an
embedded processor that did not use vtables -- I know, because part of
the job involved examining the memory layout and writing assembly code
to interact with it. The processor was the Z80, but I don't recall the
compiler or vendor.

It is simply my assumption that other C++ compilers may not use vtables,
either. Perhaps my assumption is wrong.

Quote:
I don't (currently) see how to
implement C++'s turn-off-polymorphism-during-the-ctor semantics without either
massive complexity (worse than "ordinary" PICs), vtables, or nasty run-time
tests.

The technique involved a single hidden field in each object to identify
its class. Each virtual method signature foo in some class hierarchy
would cause the compiler to synthesize a _foo_dispatch function, which
did a conditional branch based on the contents of that hidden field.
Calls to the member function would actually call _foo_dispatch, which
would jump to the appropriate code.

Although I can't guarantee this compiler did it, one could turn off
polymorphism beyond a certain superclass simply by changing the type
field.

Hi Francois,

One thought about this aspect.

The path (and even name) of your command might be different in the
different environments. It would be worth while to externalize the
definition of your command into a database or properties file that can
be changed for each environment.

If that's not explicit enough advice, a common pattenr for a main() method

public static void main(String[] args)

}



And even more explicitly:

public static void main(String[] args)
{

while (end == false)
{

GetPrincipal();
GetLoanTerms();
CalculatePayment();
CalculateAmortization();
DisplayResults();


None of those last five lines call a static method. You need to

MortPayCalc2 morty = new MortPayCalc2();
morty.GetPrincipal();
// etc...

not invoke those methods "bare."

Does it really? I had no idea. Mea culpa. Still, we could have used
the command being invoked to run the class.

I suspect they are the same as it comes 'out of the box'.

The command config. is broken into three fields, and
contains values like '$BaseName' & '$FileDir'.

..when it came to that point, I felt it was better to
ignore what TextPad was doing (right, wrong or
otherwise), and organise this from the command
line. ;-)

TextPad has menu items and hotkeys to (invoke the

That being said, I recommend the OP learn how to compile
and run from the command line, so they ..
a) have control over the process
b) understand what is possible
c) can answer questions like the one that prompted
the TextPad strand of the thread.

c) also ties into a).

Thinking about this some more, the class is not public (it's default
package-private, I think.) And it's not in any package either. So
without testing to see if two classes at in the default package can
reference each other, and with out any changes (no static main) to the
original, this would work:

public class Runner {
public static main( String [] args ) {
MortPayCalc2 morty = new MortPayCalc2();
morty.main( args );
}
}

Certainly, if you put both these classes in the same file, it would
work. (Well, and the file was called Runner.java.)

Which may explain how your class was expecting to be used. It's a
slightly different idiom than the ones we were giving you.

Hi!

Thus spake Arne Vajhøj on 05/19/2007 09:52 PM:

It is open source.

opensource != free for all...

Please keep in mind that many open source projects, namely those released
under terms of the GPL, can _not_ be freely used in commercial products.
Since JBoss is released under LGPL terms, this is not an issue here, though.
