Beware Of findFirst() And findAny()

This technical article discusses a common pitfall in Java 8 Streams when using findFirst() or findAny() after a filter. It warns that these methods can silently cause bugs if the code implicitly assumes a unique matching element without enforcing it. The post explains the problem, provides examples, and advocates for fail-fast strategies to improve code robustness and prevent data-driven errors that may only surface in production.
