How do I declare a 2D String arraylist?

Question

I want to do something like this ArrayList> mylist

How can I create it?

How can I add to the external and internal li

Answer 1

List> super2dArray = new ArrayList>()

This is an arraylist of arraylists holding strings.

Also ArrayList> mylist makes no sense, because String is not a collection/list, but I think you understood that. Future readers might not though.

See this answer to see why I chose to have List on the left side.
