chunkBy()method + test caseThe
chunkBy()method partitions the Stream into Lists according to the given classifier function. In contrast togroupBy(), this method assumes that the elements of the stream are sorted. Because of this assumption, it does not need to first collect all elements and then partition them. Instead, it can emit a List of elements when it reaches the first element that does not belong to the same chunk as the previous elements.This is useful, for example, to process datasets from a database as they are usually sorted by time or some other criteria.
