Quick summary of the talk:
- We start playing a bit with integer streams
- We soon come across lambda expressions
- We introduce the Lambda Calculus and show that it is Turing Complete.
- We look at how Java lambda expressions relate to Lambda Calculus ones
- We look at how the two differ
- We ask ourselves: are functions 1st class citizens in Java 8?
- We look at what ‘1st class functions‘ means in Haskell and Scala
- We compare Java’s approach to ‘1st class functions’ with Scala’s
- We ask ourselves:
- o are Java lambda expressions objects?
- o are Java lambda expressions syntactic sugar for anonymous instances of functional interfaces?
- o Is it possible to write a recursive lambda expression in Java 8?
- We get answers to those questions
