Scala Introduction

Programmers with some experience of programming in another language looking to get a start in Scala


Expected Duration
150 minutes

Scala mixes programming paradigms, and so presents a challenge to programmers coming from any other language. This course demystifies some of the techniques associated with Scala programming.


Scala Overview

  • start the course
  • describe the features of Scala
  • download and install the Scala binaries
  • run the Scala REPL and evaluate simple expressions
  • list the IDEs with Scala support and install the Scala plugin for Eclipse

Scala Syntax Basics

  • use variables in Scala, and describe type inference
  • use value types in Scala, and describe the immutable property
  • declare and use a function in Scala
  • create a simple class and method in Scala
  • describe objects in Scala and how everything is an object

Operations and Operators

  • use Scala collections
  • use infix notation for built-in and custom methods in Scala
  • use operators and operator overloading in Scala
  • use Java types from Scala
  • describe the use of the unit type in Scala
  • use Scala if expressions and note that if is an expression and not a statement
  • use Scala match expressions

Class Basics

  • create constructors for classes in Scala
  • create fields in Scala classes, and describe behaviors of different field types
  • use automatic getters in Scala and override them
  • use automatic setters in Scala and override them
  • declare and use singleton objects in Scala
  • use companion objects in Scala

Inheritance and Traits

  • create and use a subclass in Scala
  • use traits in Scala

Practice: Classes and Functions

  • create a Scala application that contains a class, a subclass, and a companion object
