Скачать или смотреть Contrasting the Java Streams reduce() and collect() Terminal Operations

This video explores the distinctions between Java Streams' reduce() and collect() terminal operations, particularly emphasizing their implications for parallel streams. Reduce() is tailored for creating immutable values, making it unsuitable for mutable objects in parallel streams. The video illustrates this with a factorial calculation. In contrast, collect() generates a mutable result container that is designed to be updated, exemplified by creating a unique word set from the complete works of William Shakespeare. The central point I make in this video is that while reduce() is geared towards immutable values, collect() thrives on mutability, affecting their respective suitability in parallel computing scenarios.
