Course Outline
Scala (see http://www.scala-lang.org/) is a new Functional OO language available for the Java world and the .NET world. The latest version of Scala is most aligned with the Java world (as it compiles to the same byte codes as java) and can interoperate with Java. This course aligns with this version of Scala.
Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive.
Hands-on Exercises
The completed exercises and solutions provide useful skeletons which can be used as a basis for the development of purpose built applications, including:
1. Code for database access
2. Code for a network client and server
3. Code for a graphical text editor
