java Array objects

Hi all,
I am not new to java, but I'm quite confused by this problem I've been
given. I have to create a function of this type:
public boolean checkInfo(Array info);

However, I have never used type 'Array' before and haven't yet found
info to help create an object of that type (only the ability to use
java.lang.reflect.Array functions on array types). Array objects I've
come across before are things like int[], char[], float[] and so forth,
not actual 'Array' objects. How do I use this type?

Thanks for any help,
~ickz~

There is no "common ancestor" to all Arrays except Object. The best you
could do would be to overload the function to accept all primitive arrays
(int [], long[], short[], byte[], char[], float[], double[] and
Object[]), this way enabling all array types to be passed. However, are
you sure you understood your assignment correctly? It looks like an
ulikely job.

This could be interesting. The Array class is final.
I would clarify the assignment with the Instructor/ or boss.
