Hi, fellow Java folks!
You all know how vital the Java 8 update was: functional interfaces, method references, lambda expressions, and Stream API!
Streams quickly became a beloved, widely-used feature to process sequences of elements, such as collections, in a functional style. At its core, Streams offer a clean way to represent a series of transformations and computations on data. Gone are the days when developers had to write verbose loops to filter, map, or reduce a collection. One can elegantly chain operations with Streams, making code more readable and maintainable.
Furthermore, Streams revolutionized how we think about parallelism in Java. With built-in support for parallel operations, developers can use the power of multi-core processors without diving deep into the details of multi-threading — a task that has traditionally been fraught with pitfalls.
But, as with any powerful tool, there is a risk of misuse.
And that’s what exactly I am going to talk about. Streams, while beneficial, are not a panacea, and understanding when and how to use them is…
