Can't pass last requirement
Received: "The task failed to pass testing: Be sure that the program compares arrays using the deepEquals method of the Arrays class." But I am using Arrays.deepEquals in the 30th line of code. Please help me understand what I'm doing wrong.

Feel like I'm on the right track but not sure.
I understand the nature of the boolean compare function. If true, do this, if false do second. What I'm not really understanding is why the array is not assigning a value to when true or false. I expect that is should be doing this but I'm seeing nothing when I run test output in between the loops.

I tried multiple scenarios including negatives and still no luck
I am approaching this in a different way than what has been posted by others. I ran multiple scenarios with no issues, IntelliJ passed the assignment but I couldn't get it to show complete, so I tried to submit it through the web, and it will not pass saying that I need to display the middle number.
