Answer
Use a fail-safe iterator or copy the collection.
To safely handle concurrent modifications during traversal, you can use a fail-safe iterator, like those provided by `CopyOnWriteArrayList`, or work with a copy of the collection. These approaches prevent runtime exceptions and ensure thread safety. For example, using a `CopyOnWriteArrayList` for a product catalog that is frequently updated ensures consistent iteration without risking modifications.
