OVERVIEW

Java 8 Concurrency and Reactive Programming using Project Reactor is a two-day, fast-paced coding course geared for experienced developers who have prior working knowledge of Java.

Throughout the course students learn the best practices for writing non-blocking applications in Java 8 using both the Java Concurrency Framework and the Reactor API. The course provides an in-depth view of the enhancements made to the Java Concurrency API in Java 8, allowing for the development of non-blocking asynchronous processes.
This course also covers Project Reactor. Reactor is a fourth-generation Reactive library for building non-blocking applications on the JVM based on the Reactive Streams Specification. Please note that this course is also available for RxJava.

GOALS

This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in next-level Java development skills, coupling the most current, effective techniques with the soundest industry practices. Working within in a hands-on learning environment, guided by our expert team, attendees will explore:

  • Explore Parallel programming in Java including coverage of multithreading and concurrency
  • The asynchronous, non-blocking concurrency API introduced in Java 8
  • Reactive Programming in Java using Project Reactor
  • Understand event publishers and Subscribers
  • Apply operators to Reactive events
  • Understand the concept of Backpressure
  • Properly handle exceptions in the reactive process
