ArrayExperiments.java contains methods for summing the values in a 2-dimensional array of integers. In class, we wrote code to do this using a row-wise traversal of the array. We then ended class with 2 ideas of how to sum the array using a column-wise traversal instead.
I have coded up all of our ideas from today's class. Download ArrayExperiments.java and run it in BlueJ to see which of our ideas worked.
