: Always loop through rows first ( outer ), then columns ( inner ), unless the prompt specifically demands column-major traversal.

A: Usually yes, as long as it produces the correct result. But stick to the simplest solution (nested loops) to avoid overcomplicating.

System.out.println("Class Average: " + myClass.calculateClassAverage()); System.out.println("Has Perfect Score: " + myClass.hasPerfectScore());

for (int row = 0; row < rows; row++) for (int col = 0; col < nums[row].length; col++) result[row][col] = nums[row][col] * 2;

return sum;
