Practical Scala for Java Developers

Expand all

Course Description

This Practical Scala for Java Developers training course provides an introduction to the Scala programming language. Scala is a multi-paradigm language, allowing developers to write in both functional and object-oriented styles. The language runs on the JVM, which means that Scala has access to a vast range of Java libraries, and can interoperate with Java code.

The course will introduce the main features Scala: its support for object-oriented programming, and its support for functional programming.

Supported Distributions

The course can be run on Windows, Linux or OS X.
