About

These 65 examples will make this cool-new-kid-on-the-block your steady, reliable friend. Let’s parse that. Scala is cool because it’s all the rage for big data applications, and because it manages to be more sophisticated and elegant than Java. That said, Java is a steady, reliable friend - a language you can depend upon, and in which you can express yourself. These 65 examples will help you trust Scala the way you trust Java. Each is self-contained, has its source code attached, and gets across a specific Scala use-case. Each example is simple, but not simplistic.

Style and Approach

The course will cover the installation of Scala - no worries on that front!

Features
  • The Big Ideas: Before we get to the how, we better understand the why - this course will help clarify why we even need Scala when Java serves us so well
  • The Little Details That Matter: Pattern Matching, If Expressions, For Loops & Yield: Java has if-statements, while Scala has if-expressions. Differences like these matter, this course will cover them.
  • First Class Functions are perhaps the most dramatically new feature of Scala - the foundation of functional programming support.
  • Collections - Lists, Options, the Details of fold/reduce/shift in Scala are yet another bit of the language that differs significantly from other traditional object-oriented languages. We will spend a lot of time on these topics too.
  • Classes, Companion Objects, Traits, Self Types and Dependency Injection are Scala's way of providing Object Oriented support. Some of these concepts are similar to Java - those we will skim over. Others are quite different - we will be sure to cover these in detail.
