description Overview

Change Parameter Type

This refactoring changes the expected type of an argument in a method signature (e.g., from `String` to `UUID`). The IDE automatically updates the method body to handle the conversion or throws errors at all call sites that pass the old, incompatible type, forcing the developer to explicitly handle the necessary type conversion logic.

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.
