Question 9
Correct Answer: D
The given code attempts to add elements to specific indices in an ArrayList without populating the list up to those indices first. In Java, the ArrayList's add(int index, E element) method throws an IndexOutOfBoundsException if the specified index is out of range. Initially, the ArrayList is empty, so trying to add an element at index 1 or greater will result in an IndexOutOfBoundsException. Therefore, a runtime exception is thrown.
