Scala
=====
—–
* Course Id : PROG-SCAL
* Duration : 24 Hours
Overview
—–
* Scala is an object-oriented language that supports many traditional design patterns from previous programming languages
* Scala is also a functional language with first-class functions, libraries, and immutable data structures
* No declaration is needed for variables; the Scala compiler can infer the types of most variables
* Programmers can designate multiple traits for a class, and then combine their interface and behavior
* It supports first-class objects and anonymous functions
* Scala supports concurrent and distributed computing
Pre-Requisites
—–
* Basic knowledge of Java Programming
Training Objectives
—–
* Installation and Programming in Scala
* Understand object-orientation approach
* Understand the use of functional programming techniques
* Learn about Test-driven development using Scala
* Manipulate Pattern Matching and XML in Scala
Course Structure
—–
* We provide more focus on hands-on in our technical courses (typically 80% hands-on/20% theory)
* Students get the capability to apply the material they learn to real-world problems
