When adding an item to an ArrayList whose size is equal to its capacity, a new ArrayList object with twice the capacity is created, and the elements are moved to this new ArrayList. This is done to make sure that there is enough space to add the new item without having to create a whole new ArrayList every time the current capacity is reached.
