Introduction to 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
• Data typing
• Operators and methods
• Pattern matching
• Functions
• Anonymous and nested functions
• Traits

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
• Partially specifying matches with wildcards
• Deep matching using case constructors
• Matching against collections of items
• Using extractors instead of case classes

Test Driven Development in Scala

• Writing standard JUnit tests in Scala
• Conventional TDD using the ScalaTest tool
• Behavior Driven Development using ScalaTest
• Using functional concepts in TDD

XML Manipulating in Scala

• Working with XML literals in code
• Embedding XPath like expressions
• Using Pattern Matching to process XML data
• Serializing and deserializing to and from XML

Writing Concurrent Apps

• Issues with conventional approaches to multi-threading
• How an actor-based approach helps you write thread-safe code
• The Scala architecture for creating actor-based systems
• Different coding styles supported by the actor model
