Discovering Modern Java

What you need to know about Java 9, 10, 11, and beyond

Henri Tremblay

Java continues to roll out new releases at a very fast pace. A lot of features have been added since Java 8. Some of these new features have proven to be extremely useful. For example, immutable collections and switch expressions.

In this Live Training, we will cover the following features in detail: Lambdas under the hood, parallel programming, var type inference, module system, improvement to the collection framework, type witness, pattern matching, and more. You will learn how to use reflection, the modern way or how a method reference is not always a drop-in replacement of a lambda.

You'll pick up new tricks that you can use in your code up to the latest Java version at the moment of the presentation. Stay tuned!

What you'll learn-and how you can apply it

  • How to get rid of these “Unchecked warnings” that just won’t go away
  • Java 8 lambda, streams, parallel programming tricks to make you more efficient
  • Java 9 module system to understand what it’s really about
  • Java 9, 10, 11, 12, 13, 14 new features
  • The new Java release process and why you should care

This training course is for you because...

  • You are a Java developer.
  • You want to be efficient.
  • You want to learn the magic tricks that will make you an expert
  • You don’t what to be left behind coding in Java 7 until retirement
