Java Reference Sheet

Objective: Write program code to create, traverse, and manipulate elements in 1D array or ArrayList objects.

Given a list of ints, return true if the list contains a 2 next to a 2 or a 4 next to a 4, but not both.

either24([1, 2, 2]) -> true

either24([4, 4, 1]) -> true
either24([4, 4, 1, 2, 2]) -> false

The following are methods of a list that can be used to manipulate the contained data.
