In the emptyDishwasher method, I forget to increment the index again whenever I found a spoon and dish, which caused a index out of bounds error.

I messed up

For CalcSpecialSum I forgot to declare my my integer to hold the values. I forgot the () when declaring the Arraylist. I also did row[i].length instead of arr[row].length. For the emptyDishwasher I forgot that remove(i) shifts the whole list and i put remove(i+1).

In my wholenums, I didn't do a nested for loop and was missing an Arraylist. In EmptyDishwater, i needed to make sure that the remove parameter has to be index and can't use a for each loop to remove item. I have to use a for loop.

In emptyDishwasher, I forgot quotes around "spoon" when comparing strings.

For CalcSpecialSum, I put arr.length() instead of arr.length. I also put row.length() instead of arr[row].length-1.

for EmptyDishwasher I messed my index when subtracting both i and i-1 which led to me getting a out bounds error so by adding another i -- when it removed spoon and dish it fixed my index, and I forgot to add () at the end of .size

i forgot the name of the method and the return for calcSpecialSum. For emptyDishwasher i tried to access i + 1 while letting the loop go to the last element, which gives out of bounds.

In the emptyDishwasher, I wrote for(int i = 0; i

In 2d array I forgot to add the odd sums *2 to the ArrayList.

For emptydishwasher I forgot to decrement (left to right loop) the index which cause the loop to skip over an element.

In 2D array, I have made errors with the if statements
