A Beginner's Guide to Scala, Object Orientation and Functional Programming

Scala is now an established programming language developed by Martin Oderskey and his team at the EPFL. The name Scala is derived from Sca(lable) La(nguage). Scala is a multi-paradigm language, incorporating object oriented approaches with functional programming.

Although some familiarity with standard computing concepts is assumed (such as the idea of compiling a program and executing this compiled from etc.) and with basic procedural language concepts (such as variables and allocation of values to these variables) the early chapters of the book do not assume any familiarity with object orientation nor with functional programming These chapters also step through other concepts with which the reader may not be familiar (such as list processing).

From this background, the book provides a practical introduction to both object and functional approaches using Scala. These concepts are introduced through practical experience taking the reader beyondthe level of the language syntax to the philosophy and practice of object oriented development and functional programming. Students and those actively involved in the software industry will find this comprehensive introduction to Scala invaluable.

Unlike other books currently on the market this title does not assume that the reader is already proficient in an object-oriented language such as Java All examples are complete and can be downloaded and executed by the reader As well as introducing Scala, object-oriented and functional programming the book also covers web frameworks for Scala such as Play, Scala Swing, database access, build systems for Scala and the Akka concurrency framework

John Hunt is a technology trainer, consultant, mentor and author who has 35 years experience within the computing industry. He has worked extensively in Object Oriented technologies over the last 25 years, although his career began writing LISP on a Symbolics Lisp Machine. He first encountered Scala in 2010 through an organization with which he was working. Since then he has been involved in numerous Scala projects and has worked with a number of teams on developing their Scala skills.
