description Overview

Extract Field

When several related fields are declared sequentially within a class, this refactoring groups them together and often suggests encapsulating them into a dedicated Value Object (VO) or Data Transfer Object (DTO). This improves the class's cohesion by logically grouping related data members, making the class definition cleaner and more semantic.

Replace Type Parameter

When working with generic containers (like `List` or custom generic types), this refactoring allows you to systematically replace the type argument `T` with a concrete type or another generic type across all usages. It is vital for maintaining type safety when evolving generic APIs, ensuring that all consumers of the generic structure are updated correctly.
