Java
Java drastically changed with the introduction of Java 8, and this change has been elevated
to a whole new level with the new version, Java 9. Java has a well-established past, being
more than 20 years old, but at the same time, it is new, functional, reactive, and sexy. This is
a language that developers love, and at the same time, it is the number one choice of
developer language for many enterprise projects.
It is probably more lucrative to learn Java now than ever before, starting with Java 9. We
encourage you to start your professional developer career by learning Java 9, and we have
done our best in this book to help you along this road. We assembled the topics of the book
so that it is easy to start, and you can feel the things working and moving very soon. At the
same time, we have tried to reach very far, signaling the road ahead for a professional
developer.
The sands of time kept moving, and I discovered functional programming.
I could very well see why writing side-effect-free code worked! I was hooked and started
playing with Scala, Clojure, and Erlang. Immutability was the norm here.
However, I wondered how traditional algorithms would look in a functional setting and
started learning about it.
A data structure is never mutated in place. Instead, a new version of the data structure is
created. The strategy of copy and write with maximized sharing was an intriguing one! All
that careful synchronization is simply not needed!
The languages come equipped with garbage collection. So, if a version is not needed
anymore, runtime would take care of reclaiming the memory.
All in good time, though! Reading this book will help you see that we need not sacrifice
algorithmic performance while avoiding in-place mutation!
