A Guide to Java Streams: In-Depth Tutorial With Examples
September 4, 2024 - Streams are not data structures but tools for performing operations like map-reduce transformations on collections. This functionality—java.util.stream—supports functional-style operations on streams of elements.

Not sure if its relavant cuz: game changer was released with 8 version. Now we have 21 veraion. modern IDE has visualization of streams. Reactive Java (aka rx-java) is father of all this stuff ( would be more beneficial to dive in it rather than learning small subset) Anyhow its good stuff for someone who migrating from 7th and earlier versions of Java.

Processing Data with Java SE 8 Streams, Part 1
Figure 1 illustrates the Java SE 8 code. First, we obtain a stream from the list of transactions (the data) using the stream() method available on List. Next, several operations (filter, sorted, map, collect) are chained together to form a pipeline, which can be seen as forming a query on the data.
