3. Using List.addAll() method + Collectors. We have seen that we can fill a list by repeatedly calling the add() method on every element of the stream. But instead of calling add() every time, a better approach is to replace it with a single call of the addAll() method, as shown below. This approach, however, creates an intermediate list.

From a performance standpoint, these methods should be used with caution. In many implementations they will perform costly linear searches. The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the list. The List interface provides four methods for positional (indexed) access to list elements. Lists (like Java arrays) are zero based.
