Overview

In this Java 8 course for experienced programmers, Martin Kalin introduces constructs such as lambda expressions, method references, constructor references, and the Java Streams API. This is a code-driven course for the Java programmer who wants real hands-on experience working with functional programming.

You will gain a thorough understanding of why Java 8 was introduced, how functional programming works within data pipelines, and how this functional programming style promotes terse and simple to modify code, run-time efficiency, and thread safety. You will require access to a computer loaded with Java SE 8.

Learn to program using Java 8's new functional programming constructs
Discover how functional programming fits into the data pipeline model of computing
Become familiar with lambda expressions, method references, and constructor references
Understand how functional constructs work with the Java Streams API
Gain experience programming in Java 8 with multiple hands-on code centric exercises
