To my wife Claudia and my kids:

Thank you for your patience during night-writing and other long sessions.

I love you.

To the may people I conversed at conferences as well as attendees of my talks:

Thank you for the informative and interesting conversations. Thereby I recognized, how important the matter of Java Lambdas and Streams is for you and how much information demand exists. Without you, this book would not be written.

To you, my dear reader:

Thank you for interest in this book. I hope, I could write an understandable and valuable book, which helps you to success.
