Stream API Decoded: Transforming Java Programming into an Art
In this video, we delve into the significance of Streams by starting with a demonstration where we explore code without utilizing any new Java 8 features. We gradually enhance the code using Lambdas and Method References, and then showcase how the same code can be further improved using Streams.
Next, we delve into the core concept of Streams and illustrate the differences between Streams and collections. Through engaging animations, we explain the source-pipeline-sink concept in Streams, providing a clear understanding of their functionality.
The video proceeds with practical demonstrations of generating Streams from various data structures such as lists, sets, maps, arrays, and even raw data. We also showcase how to create infinite Streams and convert them into finite ones.
To deepen your knowledge, we present demos of various intermediate and terminal operations available in Streams. These include iterate(), filter(), distinct(), skip(), limit(), sort(), dropWhile(), takeWhile(), map(), flatMap(), count(), peek(), allMatch(), anyMatch(), noneMatch(), min(), max(), findFirst(), findAny(), reduce(), collect(), toArray(), groupBy(), and partitionBy().
Furthermore, we demonstrate the laziness of Streams, illustrating how their evaluation is postponed until necessary.
Towards the end of the video, we explore the difference between Streams and Parallel Streams, while also comparing their performance through captivating demos. Finally, we touch upon the topic of the Optional class, which will be covered in the upcoming video.
