The JDK's collection framework is radically overhauled in Java 8: it has bulk operations that take functions and apply them to all elements in a collection.  The session provides an overview of the new operations and some insight into their inner workings.  The centerpiece of the new API is the interface java.util.stream.Stream.  We will explore what streams are, how they differ from collections, how their operations are executed (in parallel or sequentially), why some operations are intermediate and others terminal, why most operations are stateless, and what fluent programming is.
