Parallel Streams, CompletableFuture, and All That: Concurrency in Java 8

Kenneth Kousen, President, Kousen IT, Inc. The Java 8 (and 9) standard library includes multiple techniques for taking advantage of parallelism and concurrency, including parallel streams and the CompletableFuture class. Combined with the ExecutorService and other classes from java.util.concurrent, they give developers a wide range of choices for optimizing program speed. This session reviews the options and trade-offs involved.
