Answer
Modifying the collection can cause ConcurrentModificationException.
When using an enhanced for loop, modifying the collection directly (like removing elements) can lead to ConcurrentModificationException because the loop doesn't track changes to the collection. For example, if you try to remove products from a list while iterating, the loop will fail. Instead, use an Iterator to safely modify the list.
