Scala Programming – From Basics to Advanced

Course Introduction

Welcome to “Scala Programming – From Basics to Advanced,” a comprehensive course designed to take you from a beginner to a proficient Scala developer. Scala, known for its concise syntax and functional programming features, is a powerful language that runs on the Java Virtual Machine (JVM). This course is tailored to provide a deep understanding of Scala, making it an excellent choice for both new and experienced programmers looking to expand their skills.

Section 1: Scala Programming

In this section, students will gain a thorough grounding in Scala programming. We begin with an introduction to the language, where students will learn about Scala’s syntax, variables, and the basics of writing scripts. As we progress, we’ll delve into loops, conditions, and parameterizing arrays with types, providing a solid foundation in control structures and data manipulation.

We’ll cover essential topics such as lists, tuples, sets, and the differences between mutable (vars) and immutable (vals) data structures. Students will also learn how to create sets in tuples through scripting. The section continues with an in-depth look at classes, fields, methods, and semicolon inference, as well as singleton objects and app development in Scala.

Advanced topics include basic types, character literals, operators, arithmetic, and bitwise operations. We’ll explore rational objects, preconditions, auxiliary constructors, private fields, methods, operator definitions, and method overloading. Control structures like if expressions, while and do-while loops, for expressions, and exception handling with try expressions will be thoroughly covered. The section concludes with match expressions, variable scope, first-class functions, repeated parameters, reducing code duplication, higher-order functions, new control structures, and by-name parameters.

Section 2: Project On Scala: Employee Data Analysis

This project-based section is designed to apply the skills learned in Section 1 through a real-world scenario: Employee Data Analysis. Starting with an introduction to the project, students will set up their development environment, create project structures, and configure necessary dependencies.

The project will involve reading and manipulating CSV data using Scala, leveraging JDBC API for data insertion and fetching, and working with files from the classpath. Students will gain hands-on experience in configuring POM, understanding data structures, and executing Scala-based data analysis tasks.

Course Conclusion

By the end of this course, students will have developed a robust understanding of Scala programming, from basic concepts to advanced techniques. They will be well-equipped to handle real-world programming challenges, particularly in data analysis and application development. This course will empower students to harness the full potential of Scala, making them proficient in one of the most versatile programming languages in the industry.
