Summary

In this chapter, you have learned what the bare minimum steps to creating a Java 9 module are. You've created a simple module from scratch, as well as compiled and executed code in the module. You've also learned about a few possible error scenarios and how to handle them.

There is something missing though! Since we are dealing with a single module, we are not really leveraging the concepts of modularity here. The concepts of modularity come into play only when we have multiple modules interacting with each other. You'll see just that in action in the next chapter when you create your second Java module and set up inter-module dependency!
