# Constructor vs Factory method ### When to Use a Constructor Instead of a Factory * The creation logic is not complex * Object creation is not related to the creation of other objects, and all properties should be passed through the constructor * The client is interested in the implementation and wants to choose which Strategy pattern to use * The class is the type itself * There is no related hierarchy, so there is no need to choose from a list of concrete implementations --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
