About the course
Scala is a sophisticated language that seamlessly integrates Object-Oriented and Functional programming on the Java Virtual Machine (JVM). This 4-day intensive course provides a deep dive into Scala's powerful type system and concise syntax, designed to build robust, concurrent, and highly scalable applications.
We move from the fundamental syntax and the "Scala way" of thinking to advanced concepts like pattern matching, higher-order functions, and implicits. Participants will learn how to leverage Scala’s strong static typing to catch errors early, while utilizing its functional capabilities to write cleaner, more maintainable code. Through extensive hands-on labs, we explore the modern ecosystem - including Scala 3 features - to ensure your team is equipped for real-world enterprise development.
Instructor-led online and in-house face-to-face options are available - as part of a wider customised training programme, or as a standalone workshop, on-site at your offices or at one of many flexible meeting spaces in the UK and around the World.
-
- Think Functionally: Apply pure functions, immutability, and higher-order functions to solve complex problems.
- Master the Type System: Utilize traits, case classes, and generics for type-safe application design.
- Implement Pattern Matching: Use Scala’s advanced pattern matching to deconstruct data structures elegantly.
- Handle Concurrency: Write safe, multi-threaded code using Futures and modern concurrency patterns.
- Interoperate with Java: Seamlessly integrate Scala code with existing Java libraries and frameworks.
- Modernize with Scala 3: Understand the key improvements and syntax changes in the latest version of the language.
-
This 4-day intensive hands-on training course is designed for developers who want to learn the Scala programming language for building modern, scalable, and concurrent applications. It is ideal for:
Java Developers: Looking to evolve their skills with a more concise and powerful JVM language.
Data Engineers: Working with Big Data frameworks like Apache Spark where Scala is the primary language.
Backend Engineers: Designing high-concurrency systems and microservices.
-
Participants should have:
Object-Oriented Foundation: Solid experience in an OO language (Java is preferred, but C# or C++ is acceptable).
JVM Basics: Understanding of how the Java Virtual Machine operates is helpful.
Tools: Basic familiarity with the command line and an IDE (IntelliJ IDEA with the Scala plugin is recommended).
We can customise the training to match your team's experience and needs - with more time and coverage of fundamentals for newer developers, for instance.
-
This Scala course is available for private / custom delivery for your team - as an in-house face-to-face workshop at your location of choice, or as online instructor-led training via MS Teams (or your own preferred platform).
Get in touch to find out how we can deliver tailored training which focuses on your project requirements and learning goals.
