65 examples that will bring Scala to life for you
About This Video
 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 ifstatements, while Scala has ifexpressions. 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 objectoriented 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.
In Detail
These 65 examples will make this coolnewkidontheblock 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 selfcontained, has its source code attached, and gets across a specific Scala usecase. Each example is simple, but not simplistic.
