Answer
The next element in the iteration. Frame the concept in practical terms so you can explain it during interview discussion.
The `next()` method returns the next element in the collection's iteration sequence. This is useful for accessing each element in a loop, like retrieving the next product to process from a product catalog. It advances the iterator's position, preparing it for the subsequent call to `next()` or `remove()`.
