An Overview of Java 9

Explore the key features and changes introduced in Java 9 through this comprehensive conference talk from GOTO Berlin 2017. Dive into topics such as collection literals, minor language changes, string optimizations, and the Java Module System. Learn about modules in Java, their purpose in addressing protection scheme issues and jar hell, and how they affect development practices. Discover the new source code structure, modular development approach, and the concept of modular runtime images. Gain insights into automatic modules, module architecture, and potential critiques of the new system. Additionally, get an overview of other Java 9 features and a broad look at JDK 9 enhancements. Enhance your understanding of Java 9's improvements and prepare for the evolving Java ecosystem.
