description Overview

Extract Package

This refactoring takes a group of related classes and interfaces and moves them into a brand new, dedicated package or module. It is a structural tool that enforces the Separation of Concerns principle at the highest level. It is crucial for managing the complexity of large applications by creating clear, isolated domains within the codebase.

Extract Interface from Class

A specialized version of Extract Type, this tool specifically targets extracting the *public contract* of a class into an interface. It analyzes which methods are called externally versus which are internal implementation details, guiding the developer to define the minimal necessary public API contract. This is the safest way to prepare a class for dependency inversion.
