Few concepts in Java software development have changed how we approach writing code in Java than Java Streams. They provide a clean, declarative way to process collections and have thus become a staple in modern Java applications. However, for all their power, Streams present their own challenges, especially where flexibility, composability, and performance optimization are priorities.
What if your programming needs more expressive functional paradigms? What if you are looking for laziness and safety beyond what Streams provide and want to explore functional composition at a lower level? In this article, we will be exploring other functional programming techniques you can use in Java that do not involve using the Streams API.
