Answer:

14.

The answer is:
j < grades[i].length

grades[i] is the ith row in the 2D array and grades[i].length is the length of the sub array at the ith index. So j will increment to the value till the (length - 1) of the sub array at ith index.

The name of the method that enables us to append an element at the end of the ArrayList is add()

Suppose an ArrayList is declared as:

ArrayList<Integer> list = new ArrayList<Integer>();
and we want to append the integer 8 to the list, we write the command as:

list.add(8)

This will append 8 to the ArrayList list.
