Scala Programming for Java Developers

Scala Programming for Java Developers

Bascom Bridge’s Scala training teaches Java developers how to build applications using Scala. Scala is a programming language built on top of the JVM that integrates functional programming with Java’s object-oriented programming model, with a goal of enabling developers to build applications more rapidly and efficiently.

SCALA TRAINING OBJECTIVES

• Program in Scala
• Understand Scala’s approach to object-orientation
• Master the use of functional programming techniques in Scala
• Understand how to perform TDD (test-driven development) using Scala
• Manipulate XML in Scala
• Write concurrent applications that are thread-safe

SCALA TRAINING PREREQUISITES

Attendees should be strong Java developers planning to develop Scala applications.

SCALA TRAINING MATERIALS

All students receive comprehensive courseware and a related textbook.

SOFTWARE NEEDED FOR EACH PC:

• JDK 7 or 8 (6 could be accommodated upon request)
• A recent version of Scala installed
• Scala IDE (based on Eclipse) is recommended; we would be happy to discuss using another Scala-aware IDE if you prefer it
• For classes delivered online, all participants need either dual monitors or a separate device logged into the online session so that they can do their work on one screen and watch the instructor on the other. A separate computer connected to a projector or large screen TV would be another way for students to see the instructor’s screen simultaneously with working on their own.
