Question

What does the code 'arrayListReference.remove(i);' do?

Answer 1

The code 'arrayListReference.remove(i);' removes an element from an ArrayList at a specified index position.

Step-by-step explanation:

The code 'arrayListReference.remove(i);' is a statement in a programming language and is typically used to remove an element from an ArrayList.

The 'arrayListReference' is the reference to the ArrayList object, and 'remove(i)' is the method call to remove the element at the specified index position 'i' within the ArrayList.

For example, if you have an ArrayList with elements [10, 20, 30, 40, 50], and you call 'arrayListReference.remove(2);', it will remove the element at index 2, which is 30, resulting in the ArrayList becoming [10, 20, 40, 50].
