Howdy Cay,

I am ardent fan of your Core Java Server Faces book Way back (in 2005) I read it and I still read the way you had taken the readers from the scratch. Really glad to connect with you through Ranch on this Book Promo forum.

I have a few questions to you on the book.

1. What is the level of impatience being granted? That means what is the minimum per-requisite with which the users should start off reading this book? Java 5 or 6 or 7 ?

2. Do you intend to touch base any of the certification objectives for Java 8 ? I presume yours would be a core language book than just on certification. But still a thought!

3. To what extent you touch base the historical reasons of the new inventions - say Lambdas Vs Anonymous Inner classes etc., so that the people will still have a justifying reason of the features in Java 8?

Thanks in advance.

Hi, this book is for readers who are fluent in some other language and now want to learn modern Java. For example, if you grew up with JavaScript or Python, you'll feel right at home.

If you already know Java and want to get a crash course into Java 8, read "Java SE 8 for the *Really* Impatient" instead.

I do not explicitly cover certification. If you understand the book, you should be able to easily pass the certification exam. But it's not one of those books that teaches to the test.

I don't completely hide the past, but I focus on the present. For example, check out the sample chapter at http://www.informit.com/articles/article.aspx?p=2303960. I tell you:

- Don't put constants in interfaces. Use enums.
- Don't make utility classes like Collections or Paths any more. Just use static methods in the interface.
- Don't make AbstractX classes--use default methods.
- Use lambda expressions, not anonymous classes, when there is only one abstract method.

Cheers,

Cay
