Answer
It's not ideal when you need to modify the collection during iteration.
The enhanced for loop does not support modification of the collection (e.g., removing elements) during iteration. Attempting to do so can cause a ConcurrentModificationException. For example, if you're trying to remove out-of-stock products from a list while iterating, using an iterator with the `remove()` method is necessary to avoid runtime errors.
