In the final chapter of this book, we will tie together many of the techniques explored in the previous chapters. We will create a simple console-based application for acquiring data from Twitter and performing various types of data manipulation and analysis. Our goal in this chapter is to demonstrate a simple project exploring a variety of data science concepts and provide insights and considerations for future projects.

Specifically, the application developed in the final chapter performs several high-level tasks, including data acquisition, data cleaning, sentiment analysis, and basic statistical collection. We demonstrate these techniques using Java 8 Streams and focus on Java 8 approaches whenever possible.
