Do We Really Do Functional Programming In Java?
Conference (INTERMEDIATE level)
Taroudant B

Many developers believe that Functional Programming (FP) arrived in Java 8, with the addition of the Streams API. But is this really true?


In this talk, Ben Evans will talk about what FP really is, examine whether Java is really FP or not, consider how we could have done things differently, in another world, and also discuss recent developments in Java 17 and what lies ahead for both Java and the JVM that might enhance the functional programming capabilities of the language.
