This workshop expands on the basics of Java Lambdas and the Stream API. In this workshop, we will go beyond the introduction and basic mechanics of Lambdas and dive deeper into the variety of intermediate and terminal operations and how each of them have multiple overridden implementations within the API (and why).

During this workshop, we will build a functional Spring MVC Restful web service to demonstrate how to apply the different operations, such as:

* filter
* map
* flatMap
* reduce
* sorted
* forEach
* collect
* allMatch
* anyMatch
* count
* findAny
* findFirst
* distinct
* limit
* skip
* toArray

The review of these operations will focus on the following:

* the difference between intermediate operations and terminal operations
* which operations are short-circuiting operations
* why some operations are stateful
* what it means for some terminal operations to return an Optional
