On what criteria do you base the choice of inject in development?

The choice of dependency injection method in Java development is based on several criteria:

• Type of dependency: Constructor injection (via constructor) is preferred for mandatory dependencies as it guarantees their presence when creating an object. Setter injection is suitable for optional dependencies.
• Lifecycle management: If the object should be immutable after creation, constructor injection is better.
• Testability: Constructor injection makes testing easier as dependencies are explicitly passed.
• Framework and context: Some DI frameworks (e.g., Spring, Dagger) have their own recommendations and restrictions on injection types.

Example of constructor injection in Java using Spring:

@Component
public class Service {
    private final Repository repository;

    @Autowired
    public Service(Repository repository) {
        this.repository = repository;
    }
}
