Hi

I have an ArrayList (al) and I add Arraylists to it.
Is there a simple way to get the first item of the first arraylist?
Or the sixth item of the first arraylist?
thanks

Try ((ArrayList)al[0])[0] to get first element of the first ArrayList.
A more elegant solution is to use generic List class instead of the main array list:

List<ArrayList> arrays;

...

arrays[1][2] = 5;
