It seems to me that the author uses array so frequently that he had to come up
a "generic" method to convert Array to String. Maybe he should start to learn
to use other types of data structure (or even OOP) to solve his problme :-)

Not really, this problem is very useful in debugging. Sometimes you
want to dump large matrices, sometimes some data files has unknown dimenions
(such as raw data coming from NetCDF). I have my own multi-dimensional
data output/cloning routines for this kind of purposes.

come up
learn
For unknown dimension data, isn't it better to use dynamic dimension data
structure such as List (ordered or not) to store the data instead of static
array structure? Also you can store Lists inside List. To dubug this kind of
data structures, you can simply use/overwrite "toString()" (you can create
your own data structure as the list of List):
... class MyList {
private List _listOfList;
...
public void add (List childList) {
_listOfList.add(childList);

Gosh, sometimes it is not what you want to use, it is what you have given.
Also, access with multi-dimensional data with array is fast and simple, as
in rotation matrices. Sometimes, it is nice to have 1 routine to output
whatever array data.
