How to pass two dimensional array in Java

[aeo3]

Hi all,
I am trying to pass a two dimensional in java but there a problem in this function

    public static void doOutput(String args[], double vector[][40])

Please what is the problem in this line

As far as I know, you cannot pass size of dimensions!
And it's better to use different syntax, not C++ syntax.

So just write

public static void doOutput(String[] args, double[][] vector)

and it should work.

You can get the size of the passed array with vector.length .
By the way, in opposition to C++, each element of the array can have a different size. So vector[0].size and vector[1].size can be different!
That's much better than hardcoding the size of the second index to 40, isn't it?

Hopefully, chaarmann, you will check your PM and respond to me ....
