Answer 1

An arraylist is not an object to make a 2 dimentional arrays. However you can use it anyway : You can use :

new ArrayList>; //or
new ArrayList; 

But you should implement your own matrix class because you will probably have some check to do and a function get(int row, int column) would be cool
