Clean Code is a crucial aspect of software development that ensures our code remains understandable, modifiable, and extensible. In this course, we learn the principles of Clean Code and how to apply them in Java. The focus is on design strategies, finding the right level of abstraction, and writing elegant, expressive code.

The workshop includes the following topics:

– Introduction to Clean Code
... - Overview of Clean Code and expectations for the workshop
... - Why Clean Code matters and how to avoid perfectionism

– Effective Naming and Abstraction
... - The art of naming
... - Identifying the right level of abstraction

– Refactoring and Lean Code
... - Cognitive load as a driver for refactoring
... - Lean Code and Just-Enough-Design

– Design Strategies and Principles
... - Balance between specific and abstract code
... - Reification
... - Avoiding premature abstractions (AHA and WET principles)

– OOP & Functional Programming
... - Combining OOP with functional programming
... - Do or Die Principle (DOD)
... - SOLID, DRY, YAGNI and Law of Demeter

– Null-safe Programming and the Stepdown Rule
... - Null-safe programming
... - The Stepdown Rule

– Elegant and Expressive Code
... - Replace getters with Queries, setters with Domain Methods
... - Flatten conditionals with Monads

– Object Design and Primitive Obsession
... - Elegant Objects
... - Primitive Obsession and Value Objects

– Exception Handling and Data Classes
... - Pluggable exception handling strategies
... - Design of data classes (Lombok, Immutables, pure Java)

– Extended Collections and Dependency Injection
... - Extended Java Collections (Guava, Vavr)
... - Memoization and advanced Dependency Injection patterns (Spring)

– Test Driven Development (TDD)
... - Test-driven components

You will not only get to know these concepts but also apply them practically.

Disclaimer: The actual course content may vary from the above, depending on the trainer, implementation, duration and constellation of participants.

Whether we call it training, course, workshop or seminar, we want to pick up participants at their point and equip them with the necessary practical knowledge so that they can apply the technology directly after the training and deepen it independently.
