Our date calculator is now complete. The utility itself is not too terribly complex, although, it did serve as expected, which has to be a vehicle for experimenting with Java 8's Date/Time API. In addition to the new date/time API, we scratched the surface of regular expressions, a very powerful and complex tool to parse strings. We also revisited the command-line utility library from the last chapter, and dipped our toes in the waters of unit testing and test-driven development.
In the next chapter, we'll get a bit more ambitious and step into the world of social media, building an app to help us aggregate some of our favorite services into a single application.
