refactoring-to-patterns

You can refactor long methods using patterns like Compose Method to break them into focused, well-named helpers, and Replace Conditional with Polymorphism to simplify complex logic for easier maintenance.

Replace Conditional with Polymorphism is a refactoring pattern that moves complex conditional logic into polymorphic classes, enabling easier extension and reducing fragile class hierarchies in medium to large codebases.

Use Form Template Method when you have similar methods across class hierarchies that can share a common structure, allowing subclasses to override specific steps while maintaining consistent algorithm flow.

Eliminate code smells by identifying recurring design problems and applying proven refactoring patterns such as Introduce Null Object, State/Strategy migrations, and Compose Method to improve code quality.

Yes, you can transform a monolithic method into focused, well-named helper methods with clear abstractions using the Compose Method pattern, restructuring it into simpler components while preserving behavior.

Yes, these refactoring patterns are specifically applicable to medium to large codebases, addressing scenarios such as long methods, complex conditionals, and fragile class hierarchies with practical examples.
