Java / Concurrent collections

Explain stream pipelining in Java 8.

Stream pipelining is the concept of chaining operations together. This is done by splitting the operations that can happen on a stream into two categories, intermediate operations and terminal operations. Each intermediate operation returns an instance of Stream itself when it runs, an arbitrary number of intermediate operations can, therefore, be set up to process data forming a processing pipeline. Then there is a terminal operation which returns a final value and terminates the pipeline.
