Preface

Java 9 and its new features add to the richness of the language--one of the most-used languages to build robust software applications. Java 9 comes with a special emphasis on modularity. Some of the new features of Java 9 are groundbreaking, and if you are an experienced programmer, you will be able to make your enterprise application leaner by implementing these new features. You will be provided with practical guidance in applying the newly acquired knowledge in regards to Java 9 and further information on future developments of the Java platform. You will also work through projects from which you can draw usable examples as you work to solve your own unique challenges.
