Key Features of the Scala Language
- 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
Basic Programming 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
OO Development 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)
Functional Programming in Scala
- 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
Pattern Matching in Depth
- Writing standard JUnit tests in Scala
