In this chapter, we've looked at some guidelines and best practices to create modules and identify module boundaries. When creating a new application or when migrating an existing legacy application to Java modules, it's always a good idea to have a map of the modules and their interactions designed in advance. We've looked at some best practices that let you figure out what a module should be made of and what would cause you to segregate logic into separate modules.

We then looked at a list of best practices and ideas to use in your code. Many of the best practices discussed previously come with simplified code examples. Each example is intentionally bare-bone with code that demonstrates just the pattern being discussed and little ...
