Answer
List.copyOf creates an immutable copy; unmodifiable view wraps the original list.
List.copyOf creates a new, immutable list that doesn't reflect changes to the original collection, whereas an unmodifiable view is a wrapper that prevents modification but reflects changes made to the original list. In an e-commerce context, using List.copyOf ensures that a list of items in a shopping cart snapshot remains consistent even if the cart changes later.
