Requirements

  • Intermediate level Java programming knowledge

Description

Do you want to learn the fundamentals of the Java 8 programming platform? Would you like to be able to understand how to make use of the latest Java 8 functional programming features? Maybe you're on a new project which is based on Java 8 and you'd like a gentle introduction to how the Java 8 platform hangs together?

Then this course is for you!

I take you from knowing nothing about Java 8, assuming just an intermediate level knowledge of Java, and take you through each concept in the Java 8 platform, step by step, from first principles.

In this course you'll be introduced to and come to understand:

  • What's new in Java 8 (and why you should take notice!)

  • Lambda Expressions (what they are and how to use them)

  • Functional Interfaces (why they're important and what role they play)

  • Function Descriptors (a handy tool for understanding lambdas and functional interfaces)

  • Method References (the different types and how to use and apply them)

  • Default Methods (what they are, why they were introduced and where to use them)

  • Pipelines and Streams (understanding through example)

  • Optionals and the Optionals API (what they're for and how to use them)

This course is a concise, no-nonsense guide to Java 8 which explains just enough detail so that you can absorb and understand the core concepts and get you up and running, quickly and effectively with coding in Java 8.

I can't wait to teach you all about the exciting features of Java 8 inside! ;)

Who this course is for:

  • Beginner to intermediate level Java developers who want to understand the Java 8 platform
