Explore the fundamentals of modularity in Java through Project Jigsaw in JDK 9 in this 42-minute conference talk from Strange Loop. Delve into the significant changes that go beyond separating standard class libraries into discrete units. Understand the impact on application building, including encapsulation of previously visible private APIs. Learn about module fundamentals, declarations, dependency graphs, package visibility, and Java accessibility changes. Examine JDK 8 dependencies, JDK 9 platform modules, and compilation with module paths. Discover how to package with modular JAR files, link applications, and run them using both classpath and modules. Gain insights into automatic modules and application module dependencies to prepare for the future of Java development.
