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

Getting started

As with every application, before we get started, we need to think about what we want the application to do. That is, what are the functional requirements? At a high level, the description tells us what we want to achieve in broad terms, but, more specifically, we want the user to be able to do the following:

  • Connect to several different social media networks
  • Determine, on a network-by-network basis, which group of data (users, lists, and more) to retrieve
  • See list of items from each network in a consolidated display
  • Be able to determine from which network an item came
  • Click on an item and have it loaded in the user's default browser

In addition to this list of things the application should do, the things it shouldn't do include the following:

  • Respond/reply to items
  • Comment on items
  • Manage friends/following lists

These features would be great additions to the application, but they don't offer much that would be architecturally interesting beyond the basic application detailed previously...
