Hello,
java -jar myapplication.jar
will launch my java application. I want that this application reads some
file from a .jar file.
On the internet I found a lot of samples for this job, but of course I
need the name of the .jar file.
The name of .jar file is myapplication.jar. But how to get it ?
In Linux, with C program argv[0] is name of the program.
My question is : How can I find that the running program is
myapplication.jar ? Is there a portable mechanism
in java taht is linke the argv[0] in C context ?
Look closely at the declaration of your main method. There should be
parameters there. If not, it can be re-written. Here is an example which
you can see the parameters but they are not used. The idea behind this
was to double check and see if 25gigabytes would fit in a Long value:
public class LongValueChecker
{
Long _longValue;
public static void main ( String[] args )
{
LongValueChecker app = new LongValueChecker();
app._longValue = new Long(( new Long(27) * new Long(1073741824)
));
System.out.println ( app._longValue );
System.out.println ( Long.MAX_VALUE );
}
}
The output is:
28991029248
9223372036854775807
So in other words a Long value can hold 25 Gigabytes on the order of
tens of millions of times over.
String[] args at the main declaration is where you get arguments from.
Wirte your self an experimental program that accepts a parameter and
then prints it using System.out.println().
