Acknowledgement

At the time of writing this book, I was fortunate enough to work with an excellent team at Packt Publishing, whose contributions vastly improved the presentation of this book. Dominic Shakeshaft and Frank Pohlmann allowed me to provide ideas to develop this book, and I jumped into the exciting project of teaching object-oriented and functional programming with Java 9 using JShell as the main tool. My conversations with Frank helped me realize my vision for this book and create a robust table of contents. Radhika Atitkar provided many sensible suggestions regarding the text, the format, and the flow. The reader will notice her great work. I would like to thank my technical reviewers and proofreaders for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained in their many years in the software development industry. This book was possible because they gave valuable feedback.

The process of writing a book requires a huge amount of lonely hours. I wouldn't be able to write a book without dedicating some time to play soccer against my sons, Kevin and Brandon, and my nephew, Nicolas. Of course, I never won a match. However, I did score a few goals.
