Question: 1 / 510

What does the method 'add()' do in the context of an ArrayList?

Increments the size of the ArrayList by one

Inserts a new element into the ArrayList

The method 'add()' in the context of an ArrayList inserts a new element into the ArrayList. This adds the element to the end of the list, increasing its size. Option A is incorrect because the size of an ArrayList is not incremented by calling 'add()', but rather by adding elements to the list. Option C is incorrect because 'add()' does not update existing elements, but rather adds new ones. Option D is also incorrect because 'add()' does not delete elements, but rather adds them.
