I blogged about Java stream debugging in the past, but I skipped an important method that's worthy of a post of its own: peek. This blog post delves into the practicalities of using peek() to debug Java streams, complete with code samples and common pitfalls.
Understanding Java Streams
Java Streams represent a significant shift in how Java developers work with collections and data processing, introducing a functional approach to handling sequences of elements. Streams facilitate declarative processing of collections, enabling operations such as filter, map, reduce, and more in a fluent style. This not only makes the code more readable but also more concise compared to traditional iterative approaches.
