Java: Enterprise App Development with Java 9: 4-in-1

A lot of applications built today need to handle huge amounts of traffic in low latency. Java is a very popular language and JVM is a popular platform to build high performance programs in Java. Writing high-performance concurrent and thread-safe programs is hard, but you’ll discover how and see what Java 9 adds to the software engineer toolkit.

Java 9 comes with a rich feature set. It intends to change the way Java developers used to write code. It introduces a modular JDK so that developers can only include the modules that they need. The prospect of being one of the first to explore the brand new JDK from Java is the primary motivator. Also, this is the biggest change been introduced in Java for a while.

This comprehensive 4-in-1 course will set you on the path to become a skilled and professional Java developer by exploring Java 9 and Java EE 8 and learning how these technologies can be used to create a modern, scalable enterprise application. Comprehensive and detailed, the easy to follow tutorial will take viewers on a journey to going from zero to hero Java programmers with the new Java 9 SDK.

Contents and Overview

This training program includes 4 complete courses, carefully chosen to give you the most comprehensive training possible.

The first course, Java 9 Core Principles, covers exciting real-world examples with Java. As you progress in your journey, you will encounter more advanced topics including functional data processing, before investigating how you can build fast, scalable APIs for the connected web. In the final section, you will build an API to analyze the sentiment of sentences provided by the user, along with various statistics about your API.

The second course, Java 9 New Features Deep Dive, covers new modular programming concept in Java 9 and know how it will affect you and your clients ahead of time.We will start up with the setting up of Java 9 and learn the modularization concepts and then proceed to deployment. This should be hands on look at Java 9, but no one will be using it to make real-world applications yet. This is an assessment video for the millions of Java developers out there looking to put it to the test.

The third course, Writing High Performance Java Application in Java 9, covers how to monitor applications and write code in high concurrent with the proper tools. First, we’ll create efficient lock-free programs that leverage the multi-core architecture of the CPU using the newest Java 9 features. Then you’ll see how Java Memory Model affects the performance of your programs. You’ll discover why it’s even more important to be aware of the software-hardware co-operation of your programs in Java 9. Moving on, you’ll find out how to leverage constructs from JAVA 9 java.util.concurrent to create efficient multi-threaded programs. We’ll explore the different kinds of locking available in JAVA 9 and get to know when you should use which kind of locks. Finally, you’ll see what tools are shipped with the JDK 9 and know how to use them properly.

The fourth course, Hands-On Enterprise Application Development with Java 9, covers modern and scalable enterprise applications using Java 9 and Java EE 8 and become a professional Java developer. We will use case studies to explore how we can use the JEE8 technologies of JSF, EJB, and JPA to build a database-driven website, while all the time working with new Java 9 constructs. You’ll learn how to extract a component from our website as a standalone microservice and decouple your microservice to allow it to be reused within an organization. We will then delve into Java 9 technologies such as JShell, modules, the Streams API, Multi-Jar, Process APIs, and HTTP/2 clients.

By the end of the course, you’ll get up and running with Java with exciting real-world examples to monitor applications and write code in high concurrent with the proper tools leveraging Java Concurrency.
