About Mastering Java 8 Fundamentals
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
