Answer
ArrayList is faster for random access, LinkedList for frequent insertions.
ArrayList provides O(1) random access but slow insertions/deletions, while LinkedList offers efficient insertions/deletions but slow random access. For example, use ArrayList for a catalog with frequent lookups, and LinkedList when frequently adding/removing products.
