That was the second Cay Horstmann’s book ive read. First one was Core Java Server Faces .
What can i cay, this book is great. Scala language is very friendly for the newcomers, and on the other side it’s very complicated and needs a lot of practice. But it’s almost impossible to tell about all the features of one language in a three hundred pages book. But Cay Horstmann really did that. He doesn’t waste your time on an explanation of basic stuff. He goes straight to the core of Scala.
I read that book in a couple of days. If you need something to teach yourself Scala and you don’t have too much time that’s your perfect solution!
