Codehs 8.1.5 Manipulating 2d Arrays

// Sum of a specific row int rowSum = 0; for (int col = 0; col < matrix[rowIndex].length; col++) rowSum += matrix[rowIndex][col];

Ensure your loop conditions use < rather than <= . If an array has a length of 5, the last index is 4. Using <= will trigger an ArrayIndexOutOfBoundsException . Why This Matters Codehs 8.1.5 Manipulating 2d Arrays

To manipulate a 2D array, you generally use this standard structure: // Sum of a specific row int rowSum

: fixArray(array, 1, array[1].length - 1, totalElements); for (int col = 0

return sum;
