Scala

Overview

This course introduces learners to Scala, a versatile language widely used in big data and enterprise environments. It begins with setting up the environment and writing simple programs before moving into core programming constructs like variables, functions, and control flow. Learners will explore both object-oriented and functional programming paradigms, work with collections and data transformations, and gain exposure to Apache Spark through hands-on exercises. The course concludes with a mini-project that integrates multiple concepts into a practical application.

Objectives

• Understand the basics of Scala syntax, variables, data types, and control structures.
• Apply functional and object-oriented programming principles using Scala collections and functions.
• Develop skills in handling exceptions, file operations, and working with Apache Spark using Scala.

Key topics

• Introduction to Scala and its features
• Control flow and function definitions
• Object-oriented and functional programming concepts
• Collections and data processing in Scala
• Scala for Apache Spark and big data applications

Expected outcomes

• Build and run basic Scala programs including calculator and pattern printing utilities.
• Implement data transformation and analysis tasks using Scala collections and Spark.
• Create a complete student management system with file storage and reporting features.
