Programming Tutorials

Excellent Free Tutorials to Learn Scala

Scala is a modern, object-functional, multi-paradigm, Java-based programming and scripting language that’s released under the Apache License 2.0. It blends functional and object-oriented programming models. Scala introduces several innovative language constructs. It improves on Java’s support for object-oriented programming by traits, which are stackable and cannot have constructor parameters. It also offers closures, a feature that dynamic languages like Python and Ruby have adopted.

Scala is particularly useful for building cloud-based/deliverable Software as a Service (SaaS) online applications, and is also proficient to develop traditional, imperative code.

The language helps programmers write tighter code. It uses a number of techniques to cut down on unnecessary syntax, which helps to make code succinct. Typically, code sizes are reduced by an order of 2 or 3 compared to an equivalent Java application.

Here’s our recommended tutorials to learn Scala. If you’re looking for free Scala programming books, check here.

1. A Scala Tutorial for Java Programmers by Michel Schinz and Philipp Haller

This document gives a quick introduction to the Scala language and compiler. It is intended for people who already have some programming experience and want an overview of what they can do with Scala. A basic knowledge of object-oriented programming, especially in Java, is assumed.
