Getting Started with Gradle and the Spark Framework

The author, Eddie Zaneski, aims to show that it's easy to build a cool web app using Java with the Spark Framework. The author starts by creating a new Gradle project and configuring it to use the Spark Framework and Twilio SDK for SMS and voice calls. With 7 simple lines of code, the author is able to spin up a serving totally rad caffeinated HTTP request. The author then tweaks the code to receive an SMS with the name of a song, respond with a phone call, and play a snippet of the song using the Spotify API. The completed code creates a complete web app that demonstrates how easy it can be to build a web app in Java using Spark and other libraries.
