Java parallel streams7/1/2023 ![]() The Map is not supported directly, we can create a stream of map keys, values or entries. The terminal operations return a result of a certain type, and intermediate operations return the stream itself so we can chain multiple methods in a row to perform the operation in multiple steps. Stream operations are either intermediate or terminal. In Java, interface represents a stream on which one or more operations can be performed. This is a form of a producer-consumer relationship. The idea is that a user will extract only the values they require from a Stream, and these elements are produced invisibly to the user, as and when required. This concept gives rise to significant programming benefits. While a Stream is conceptually a pipeline in which elements are computed on demand. A Collection is an in-memory data structure that holds all the data structure’s values.Įvery element in the Collection has to be computed before it can be added to the Collection. This is called video streaming.Īt a very high level, we can think of the small portions of the video file as a stream and the whole video as a Collection.Īt the granular level, the difference between a Collection and a Stream is to do with when the things are computed. ![]() we don’t need to download the complete video before we start watching it. ![]() When we start watching a video, a small portion of the video file is first loaded into our computer and starts playing. ![]() What is a Stream? Stream vs Collection?Īll of us have watched online videos on Youtube. ![]()
