You have to check all elements in stream. You can collect all filtered elements to LinkedList and get the last one.
forloebs.stream()
.filter(predicate)
.collect(Collectors.toCollection(LinkedList::new)).peekLast();
peekLast will return null if this list is empty.
You can use the max function to get latest incident that matches your completeincident condition.
Optional<Incident> latestIncident = forloebs.stream()
.filter(completeincident)
.max(Comparator.comparing(x -> x.getDateIncident()));
The comparator will keep the latest element based on getDateIncident.
It will return Optional.Empty if none of them matches filter criteria.
