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

Looking around

The JVM has supported alternative languages for years. Some of the better known ones include Groovy and Scala. Both of these languages have influenced Java in one way or another over the years, but, like any language, they are not without their problems. Many feel that Groovy doesn't perform as well as Java (though the invokedynamic bytecode instruction is supposed to have addressed that), and many find Groovy's more dynamic nature less appealing. Scala, on the other hand, suffers (fairly or not, depending on who you ask) from the perception that it's too complex. Compilation time is also a common complaint. Also, many organizations are quite happily using both, so they are definitely worth considering to see if they will work in your environment and for your needs.

While those may be great languages, we are taking some time here to see what's next, and there are at least two languages that seem to stand out from the crowd--Ceylon and Kotlin. We can't give each of these languages...
