Please how do insert into and retrieve from an arraylist of arraylists

There is no such thing as a multidimensional list.

You add and get elements exactly the same way as for any other List

List<List<Foo>> myList;
 . . .
myList = new ArrayList<List<Foo>>();
 . . .
List<Foo> fooList1 = new ArrayList<Foo>();
fooList.add(f1);
fooList.add(f2);
 . . .
myList.add(fooList1);
 . . .
List<Foo> foos = myList.get(123);
 . . .
Foo fff = myList.get(123).get(234);
