Join experts Richard Warburton and Raoul-Gabriel Urma to learn how to make effective use of the new features in Java 8.
Why learn Java 8 now? With the most groundbreaking changes in its 20-year history, Java 8 incorporates some of the best ideas from functional programming. Its resulting flexible code is considerably easier to read and better for scaling workloads on multicore machines. This places Java soundly on the forefront of functional programming with other functional, JVM-based languages such as Scala and Clojure. In the months since its release, Java 8’s initial rough spots have been worked out and best practices established, making it the ideal time to upgrade all of your applications.
In this course, you’ll develop a working knowledge of the most important features in Java 8: lambdas, streams, and collectors. You’ll also become familiar with the programming tactics needed to produce functional code that’s both flexible and concise. If you haven’t dared to make the move yet or haven’t known where to begin, this training will equip you with the knowledge you need—along with hands-on instructor-led experience—to ease you through the learning curve so you can upgrade your apps with confidence.

What you’ll learn—and how you can apply it
You’ll learn how to write lambda expressions and how to process collections in a functional and declarative manner rather than using the legacy imperative techniques, which leads to writing code that can be parallelized automatically.
The features that you’ll master in this course are exceedingly powerful and offer great opportunities for writing more reliable, maintainable, faster code. Ideally, teams will learn about these features together for a common understanding of the idioms as well as which best practices the team should adopt together. This allows your team to migrate more easily to Java 8, without leaving any members behind.
The course uses a mix of lectures, ebook downloads, Q&A sessions, and live coding examples. The instructors will include simple quizzes throughout the course to track your progress. They’ll also provide hands-on exercises in which you code toward passing unit tests.
Who should attend
This course is for experienced Java developers and software architects who are interested in learning how to write functional code with Java 8 Lambdas, Streams, and Collectors. Teams will find it useful to attend the training course together so they can work with a shared understanding of Java 8 and its capabilities.
Prerequisites:
- familiarity with the Java programming language
- able to write basic core Java code (Java SE), including using classes, interfaces and basic control flow statements such as if statements and for loops
- know how to run unit tests using Junit

Richard Warburton is an empirical technologist and solver of deep-dive technical problems. Recently he has worked on data analytics for high performance computing and authored Java 8 Lambdas for O’Reilly. He is a leader in the London Java Community and organized the Adopt-a-JSR programs for Lambdas and Date and Time in Java 8. Richard also frequently speaks at conferences, and has presented at JavaOne, DevoxxUK, Geecon, Jfokus and JAX London. He obtained a PhD in Computer Science from The University of Warwick, where his research focused on compiler theory. You can follow Richard on Twitter @RichardWarburto.
Raoul-Gabriel Urma is an author of the bestselling book Java 8 in Action (Manning) as well as the new report Introducing Java 8 for O’Reilly. He has worked as a software engineer for Oracle’s Java Platform Group, as well as for Google’s Python team, eBay, and Goldman Sachs.
An instructor and frequent conference speaker, he recently completed a PhD in Computer Science at the University of Cambridge. He is also co-founder of Cambridge Coding Academy and a Fellow of the Royal Society of Arts.
