Discovering Modern Java
What you need to know about Java 9, 10, 11, and beyond
Java continues to roll out new releases at a very fast pace. We are now nearing Java 12. 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, streams, parallel programming, var type inference, module system, improvement to the collection framework, type witness, method handles 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 like how to create a tuple and assign it to a var, and look under the hood at a lambda implementation.
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 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
- This is not an introduction to Java. Attendees can be beginners but not first-timers.
- Really light look at Java 8 new lambda and stream. Start reading Java Generics and Collections – Maurice Naftalin
- Really light look at Java 9 module system. Start reading Java 9 Modularity – Sander Mak, Paul Bakker
