Encouraging and supporting my transition from Java...
on January 22, 2011
I have found the presentation in the book to be awesome for my 15 years experience with Java. Each "new" concept is introduced at just the right level of the abstraction (this is the syntax), concreteness (here's an example usage - i.e. an aspect of the semantics) and then a pleasant mildly judgmental comparison to how the same is currently accomplished in Java (1.5 or higher). I also like how principled and consistent the authors remain as they present code and design patterns. It reminded me of my experience reading Bertrand Meyer's "Object Oriented Software Design" back in 1997. There is a very deep consistency and pleasantness to every aspect of Scala. It clearly has learned immense amounts from C/C++, Java, Eiffel, Modula 2, Lisp, Erlang, Hackell, etc.
Thanks to Oracle's recent acquisition of Sun (2010), I started looking for my "what's next after Java" as I have little confidence Oracle will be as good to the future of Java as Sun had been. I like that Scala integrates so naturally with Java code. I like how there is activity to integrate it with C#/.NET. Scala really does feel like the "next thing after Java" just as Java was the "next thing" after C/C++ 15 years ago. It's core is now sufficiently stable, I can see Scala eventually compiling to targets outside of the JVM.
"Programming in Scala - 2nd Edition" has held me mesmerized throughout. I haven't been able to put it down. I have the ebook version (too) loaded in my phone and I read it every spare moment I get. I am being quite literal in that I cannot put it down. And I cannot wait to dive in and play with the language, while never being very far from all the Java libraries I have learned to depend upon over the years. The book and the language seem to be a perfect balance of encouraging a movement towards Scala like thinking while completely supporting total integration with Java 1.5 (or later) code today. I have not felt this inspired for a new language since my adoption of Java in late 1997.
Summary: Excellent at selling and teaching Scala to a long-time Java code-head
