What if everything you knew about refactoring Java code was incomplete? Stefano Violetta draws from his extensive development experience to offer a fresh perspective on improving code maintainability and design. You'll learn how to identify code smells, apply polymorphism over conditionals, and leverage automated refactoring tools through clear real-world examples and case studies, especially highlighted in the chapters on testing methodologies and architecture design. This book suits Java developers, architects, and technical leads eager to deepen their practical skills and streamline workflows without getting lost in theoretical jargon.

During his years coaching software teams, Skylar Robert Watson developed a method to tackle large-scale code changes without disrupting continuous integration workflows. This book walks you through a practical process of extracting services from a Java Spring Boot application using micro-commits, which helps avoid the pitfalls of merge conflicts in collaborative projects. You'll find detailed refactoring techniques and strategies for managing dependencies and incremental changes that can be applied directly to your own codebase. If you work in a team environment facing complexities in service extraction, this book offers a focused approach to break down those challenges into manageable steps.

Unlike most refactoring books that focus purely on abstract techniques, Matt Eland grounds his advice in the realities of modern .NET development using C# 12 and .NET 8. You’ll learn not just how to identify and address technical debt but how to leverage advanced tools like Roslyn analyzers, AI-assisted GitHub Copilot Chat, and testing libraries such as Moq and Snapper to refactor safely and efficiently. Chapters on SOLID principles and defensive coding provide concrete guidance on maintainable code, while the book’s later sections tackle the often overlooked challenge of communicating technical debt in agile and enterprise settings. This is a resource for developers at all levels who want to improve legacy code without risking stability.

This tailored book explores the evolving landscape of refactoring techniques with a keen eye on upcoming challenges and discoveries expected in 2025. It examines step-by-step plans designed to help you navigate complex codebases and emerging development paradigms effectively. By focusing on your interests and background, this personalized guide reveals how to stay ahead of innovations like AI-assisted code analysis and micro-commit workflows, offering a forward-looking perspective on refactoring journeys.
