Hi,

Sorry for the multipost. I apologize.

Here is the script that I try to run:

*****************************************************
use Inline Java => <<'EOJ';
public class TestJavaClass
{

public float[ ] [ ] returnArrayData(){
.
.
.
return ArrayData[m][n];
}

}

EOJ

my @mylist = TestJavaClass. returnArrayData();

print "$mylist[0]";

*****************************************************

I got the following output:

Inline::Java::Array=ARRAY(0xa52e234)

When you respond on this list you're asked to quote the attribution
and some appropriate context. Also this script does not look
"complete".

Anyway, you've said your problem is accessing a 2D array, so why are
you only printing the first dimension? In fact, when you do, Perl is
telling you that that first dimension is itself made up of an array.
This is as it should be.

If you're passing a 2D array, you need to access it in two dimensions.

print $mylist[0][0];

for instance should work, but I'm unable to verify it.

PS: read perldoc -q vars
