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 beyond the 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.

Scala programming is a general-purpose computer language that supports both object-oriented and functional styles of programming on a larger scale. Scala is a strong static type of programming language and is influenced by the Java programming language. One of the best similarities of Scala and Java is that you can code Scala just the same way that you code Java. It is also possible to use a lot of Java libraries within Scala along with many of its third-party libraries.Scala has become one of the most in-demand technology among developers and is working its way through today's technology. Learn about Apache Spark from Cloudera Spark Training and excel in your career as a Scala Specialist. Here are some of the topics which would give you a brief explanation of Scala.Why Scala?The biggest strength of Scala is its flexibility in defining abstractions. One of the important components of the Scala language is Scala IDE (Scala Integrated Development Environment) and it is used to connect to the Eclipse Java tool. This way the Eclipse features can explore with the Scala IDE. Scala is designed in such a way that it can inter-operate well with JRE (Java Runtime Environment) and the .NET Framework.The code written in Scala is easier to test and reuse; the parallelization becomes simpler, and there are lesser bugs in the whole program. Scala programming follows a top-down approach; each of the programs is broken down into multiple chunks and each can be processed in parallel thus speeding up the process and also improving the efficiency.

Learn the latest version of Scala through simple, practical examples. This book introduces you to the Scala programming language, its object-oriented and functional programming characteristics, and then guides you through Scala constructs and libraries that allow you to assemble small components into high-performance, scalable systems. Beginning Scala 3 explores new Scala 3 language features such as Top-level declarations, Creator applications, Extension methods to add extra functionality to existing types, and Enums. You will also learn new ways to manipulate types via Union types, intersection, literal, and opaque type aliases. Additionally, you’ll see how Implicits are replaced by given and using clauses. After reading this book, you will understand why Scala is judiciously used for critical business applications by leading companies such as Twitter, LinkedIn, Foursquare, the Guardian, Morgan Stanley, Credit Suisse, UBS, and HSBC – and you will be able to use it in your own projects. What You Will Learn Get started with Scala 3 or Scala language programming in general Understand how to utilitze OOP in Scala Perform functional programming in Scala Master the use of Scala collections, traits and implicits Leverage Java and Scala interopability Employ Scala for DSL programming Use patterns and best practices in Scala Who This Book Is For Those with a background in Java and/or Kotlin who are new to Scala. This book is also for those with some prior Scala experience who want to learn Scala version 3.
