Project Jigsaw is the star attraction of Java 9. It introduces the Java Platform Module System (JPMS) and makes it possible to create modular applications natively in Java. Modularity is key in managing complexity in modern applications but is also a complex subject in it of itself that impacts the entirety of an application.

In this course, instructor Nick Maiorano breaks down this complexity by explaining what modularity is all about, how Java has adopted modularity and how to start using to build better quality applications.

Topics include:

• What is modularity?
  
• The five pillars of modularity
  
• Modularity in the real world
  
• JPMS concepts and syntax
  
• Designing and implementing a modular structure
  
• Dependencies
  
• Compiling, packaging and running modular applications
  
• Using the dependency checking tools
  
• Creating custom runtime images
  
• Managing backward compatibility with classes and modules
  
• Explicit, unnamed, and automatic modules
  
• JPMS tips and recommendations
