Which method do you use to access elements in an ArrayList?

  1. get(int index)

  2. access(int index)

  3. elementAt(int index)

  4. indexOf(Object o)

The correct answer is: get(int index)

The method used to access elements in an ArrayList is get(int index). Option A is correct because it is the actual method that is used to retrieve the element at the specified index in an ArrayList. Option B is incorrect because there is no method called access in the ArrayList class. Option C is incorrect because elementAt() is a method used for accessing elements in a Vector, not in an ArrayList. Option D is incorrect because indexOf() is used to find the index of a specified element, not to access an element.
