Overview of this book

Java 9 and its new features add to the richness of the language; Java is one of the languages most used by developers to build robust software applications. Java 9 comes with a special emphasis on modularity with its integration with Jigsaw. This course is your one-stop guide to mastering the language. You'll be provided with an overview and explanation of the new features introduced in Java 9 and the importance of the new APIs and enhancements. Some new features of Java 9 are ground-breaking; if you are an experienced programmer, you will be able to make your enterprise applications leaner by learning these new features. You'll be provided with practical guidance in applying your newly acquired knowledge of Java 9 and further information on future developments of the Java platform. This course will improve your productivity, making your applications faster. Next, you'll go on to implement everything you've learned by building 10 cool projects. You will learn to build an email filter that separates spam messages from all your inboxes, a social media aggregator app that will help you efficiently track various feeds, and a microservice for a client/server note application, to name just a few. By the end of this course, you will be well acquainted with Java 9 features and able to build your own applications and projects. This Learning Path contains the best content from the following two recently published Packt products: • Mastering Java 9 • Java 9 Programming Blueprints

Taking Notes with Monumentum


Now we're back to the familiar refrain--our application is finished. What have we covered in the chapter? We've created a REST API using JAX-RS that doesn't require direct JSON manipulation. We've learned how to apply request filters to JAX-RS endpoints to restrict access to authenticated users, which we authenticate against their Google accounts using Google's OAuth2 workflow. We've packaged the application using Payara Micro, a great option to develop microservices, and we've integrated MongoDB into our application using the MongoDB Java API. Finally, we built a very basic JavaScript client using Vue.js to access our application.

There are a lot of new concepts and technologies interacting in this application, which makes it interesting from a technical perspective, but there's still more that could be done. The application could use a great deal of styling, and support for embedded images and videos would be nice, as would a mobile client. There is lots of room for improvements...
