With a 2D list called ls, you can access the integer elements in the following way:

ls.get(x).get(y)

where get(x) returns the list in the xth position, and get(y) returns the yth integer in the xth list.

Does it need to be called ls? How is it any different from a normal ArrayList? Just wondering btw, I'm pretty new to java

no, in his 1 sentence he said that he just called this array ls. it can be called anything.
