Scala Training Overview
Accelebrate’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.
Location and Pricing
Accelebrate offers instructor-led enterprise training for groups of 3 or more online or at your site. Most Accelebrate classes can be flexibly scheduled for your group, including delivery in half-day segments across a week or set of weeks. To receive a customized proposal and price quote for private corporate training on-site or online, please contact us.
In addition, some courses are available as live, instructor-led training from one of our partners.
