When traversing elements, which list — ArrayList or LinkedList — shows better performance?

When iterating over elements, both lists — ArrayList and LinkedList — show approximately the same performance, as both implement the List interface and support sequential access.
However, ArrayList is usually faster during iteration because it stores elements in a contiguous array, which improves data locality and cache performance.
LinkedList stores elements in nodes linked by references, so iteration involves following links, which can be slower due to lower data locality.
Therefore, for simple iteration over elements, it is preferable to use ArrayList.
