Modern java is advancing at a rapid pace. And as a developer tinkering with FP since 2010, I could see all the ideas, goodness, paradigms, thought-processes which are there in other language/ecosystem like Haskell, Scala, Clojure etc..could easily be brought into modern Java. On a day-to-day basis if these concepts are inculcated in medium to big JAVA enterprise projects we can reap significant benefits across multiple areas -

1.  Reduced tech-debt

2.  Better re-usability

3.  Improved Error/Edge case handling 

4. Reduced complexity

In my previous talk  2019, we mostly discussed about the benefits of switching to FP side of java. In this talk we are going to go deep into FP practices followed elsewhere and how to bring in enterprise java projects with concrete examples

Even though there was a delay; but JAVA has been catching up quite nicely when it comes to FP. With frequent releases and feature inclusions at a faster pace, the FP landscape in JAVA is becoming better and better every day. A lot of cutting edge projects(inspired by other languages like clojure, scala, oCaml, haskell, F# etc..) with their high-end/superior APIs complementing the language. The best part is these are just not syntactic sugars; the underlying impact of functional programming(from the language as well as the libraries) when analyzed deeply is extremely enriching and profound. The KPIs which can directly get a face-lift is a lot

1. Reduced dev/unit-testing effort

2. Less boilerplate code

3. Less mutation and higher thread safety

4. High perf persistent data-structures

5. Proven performance improvement, reduced allocation and higher throughput

Developers who have been practicing java/jvm languages for several years will find this really appealing and intriguing.
