Java Functional Programming Tutorial - 02

Java Functional Programming Tutorial. Important Functional Programming Concepts - Lambda Expression, Stream and Operations on a Stream (Intermediate Operations - Sort, Distinct, Filter, Map and Terminal Operations - max, min, collect to List), Functional Interfaces - Predicate Interface,Consumer Interface, Function Inteface for Mapping, Method References - static and instance methods

Java is one of the most popular object oriented programming languages. We take an hands-on approach using a combination of JShell(An awesome new feature in Java 9) and Eclipse as an IDE to illustrate more than 200 Java Coding Exercises, Puzzles and Code Examples.

Why reduce does not return optional? It can also have return a value or empty when the list is empy.
