Stream collect() method takes elements from a stream and stores them in a collection.collect(Collector.toSet()) collects elements from a stream to a Set.
Stream.collect() method can be used to collect elements of a stream in a container. The Collector which is returned by Collectors.toSet() can be passed that accumulates the elements of stream into a new Set.
