Scala is a relatively new language which integrates seamlessly into the Java platform. It provides an implicitly typed alternative to Java which is not limited by the constraints of backward compatibility. Scala was designed as a hybrid language that combines full object-orientation with the core features of functional programming, making it an ideal choice for tasks such as highly concurrent applications and XML manipulation. This course provides a high speed introduction to Scala for experienced Java developers. It does not waste time rehashing familiar territory but instead builds on top of delegates existing knowledge. By the end of the course delegates will be able to write and test JSE applications using all the features of the Scala language.

About this course

By the end of the course delegates will be able to write and test JSE applications using all the features of the Scala language.

Experienced Java developers who want to quickly learn the Scala language

Delegates must have a minimum of three years commercial Java programming experience. Knowledge of the basics of Test-Driven Development is helpful, as is prior exposure to functional programming concepts (via Lisp, XSLT, F# etc…).

None

Course can be flexible and tailored to suit needs of the delegates

The Evolution of Scala
  • A brief history of the Java platform to date
  • Distinguishing between the Java language and platform
  • Pain points when using Java for software development
  • Possible criteria for an improved version of Java
  • How and why the Scala language was created
Key Features of the Scala Language
  • Everything is an object
  • Class declarations are simplified
  • Data typing is strong but mostly inferred
  • Operators are methods and methods can be operators
  • There is very powerful support for pattern matching
  • Functions are values and first class citizens
  • Anonymous and nested functions are supported
  • Traits are used instead of interfaces
Basic Programming in Scala
  • Built in types, literals and operators
  • Testing for equality of state and reference
  • Conditionals, simple matching and external iteration
  • Working with lists, arrays, sets and maps
  • Throwing and catching exceptions
  • Adding annotations to your code
  • Using standard Java libraries
OO Development in Scala
  • A minimal class declaration
  • Understanding primary constructors
  • Specifying alternative constructors
  • Declaring and overriding methods
  • Creating base classes and class hierarchies
  • Creating traits and mixing them into classes
  • How a Scala inheritance tree is linearized
Functional Programming in Scala
  • Advanced uses of for expressions
  • Understanding function values and closures
  • Using closures to create internal iterators
  • Creating and using higher order functions
  • Practical examples of higher order functions
  • Currying and partially applied functions
  • Creating your own Domain Specific Languages (DSL’s)
Pattern Matching in Depth
  • Using the match keyword to return a value
  • Using case classes for pattern matching
  • Adding pattern guards to match conditions
