Answer
By returning a copy or an unmodifiable view.
To prevent external modifications, return a copy of the list or use `Collections.unmodifiableList()` to provide a read-only view. This prevents the caller from altering the original list. For instance, a `Customer` class might provide a method to return an unmodifiable list of their orders.
