You're going to want to set up a placeholder 1D array of integers that you'll return later, and loop through the 2D array of dice. As the question states, you'll want to roll each die within the 2D array while also updating that placeholder int[] array from before if the current die being checked has an even face value. If it is even, you want to increment the int[] array's value at the index position equal to the row that the current die is in. Use an array similar to this one to test (you can also set up the Die objects one by one lol:   Here's how the logic works:
