I have an ArrayList with type length 2 int[]. ArrayList<int[]>
What I want to do is sort the ArrayList by increasing order of the second element of int[1].
Is there any built-in method to do this?

`arrayList.sort((p1, p2) -> p1[1] < p2[1]);` – flakes Oct 28 '16 at 19:26

Or `Comparator.comparingInt(p -> p[1])`. – Tunaki Oct 28 '16 at 19:29

I don't understand what p and [1] stand for – KCoder Oct 28 '16 at 19:32
