Course Description

Scala is a programming language designed to include advantages from both object-oriented and functional programming paradigms. It is a concise, agile, and scalable language that can handle lots of data in real time. Scala is a popular choice for many open source and Big Data projects. The prominent Big Data framework, Apache Spark, is also developed using Scala.

Adastra Academy’s ‘Scala in Practice’ includes a general overview, the benefits of programming in Scala, and several hands-on exercises. Unlike other courses, students taking ‘Scala in Practice’ quickly become proficient in coding and develop a Mobile App as part of the course work. We also explore Scala’s main features that make it a unique programming language and various enterprise applications to understand why it is more often deployed than others.

Section 1: Introduction to Scala and Environment Setup
7 pages

This lecture contains the detailed installation guide and the setting up tools and environment for developing codes in Scala.

Introduction to Scala

In this lecture, there is a description of basic types and basic operations and finally how to define a basic function in Scala.

Section 2: Collections in Scala
In this section, the difference between mutable and immutable collections is introduced. It also provides examples of some of the most used collection types and finally some methods from Scala’s collection library.
Section 3: Parallelism and Concurrency Concepts in Scala
In this section the concept of Parallelism and some examples of how to make collections parallel followed by a discussion on an improved threading model (Actors) in the Akka package are discussed. The last topic in this section is Lazy Evaluation which is useful when dealing with values that are not needed immediately and whose computational cost is significant.
Hands-on Exercises Code in Scala Worksheet
Section 4: Object-oriented Paradigm
In this section we are going to cover the definition of Classes and Objects, then we provide some examples for Case classes and Pattern Matching. Followed by Overriding. Trait, which is generalization of Java's interface and allows multiple inheritance is discussed next. Then polymorphism concept, parameterized function/classes/trait is discussed with examples followed by the important feature which is interoperability between Java and Scala programming languages.

Section 5: Functional Programming Principles in Scala
In this section, we are going to cover the concept of functional programming, the difference between call-by-value and call-by-name, recursion and tail recursion. Then the concepts of Higher-order functions and Nested functions are discussed along with some examples of the functions in Scala. At the end of the section, there is an introduction to For Expression along with examples to show how For Expression is used to make programming in Scala easier in some cases.
