Embrace the Func - How Far has Functional Programming Come in Java?
summary
Live-coding shows Java can use records are immutable by design, pure functions that return new objects, and Function/Stream composition to transform a music-album dataset (format names, sum durations, detect various artists). It demonstrates destructuring with record patterns, higher‑order lambdas, and practical limits: lists are mutable so defensive copies are needed and frameworks like Hibernate force mutable beans. The conclusion is pragmatic: functional style is possible and helps concurrency, but verbosity and ecosystem constraints block full adoption.
