Creating arraylist of arraylist from string? - index.of string jpg

I'm trying to create an ArrayList of ArrayList with names taken from the vocal lines.

For example, the text file ..

Obama, McCain, Clinton
Bush, Clinton,
Paul, Washington, Adams,

ArrayLists create three, arrayist each name as an index of the individual in an ArrayList. I think, created by the method of the distribution chain, but only one table. What would you suggest?
