What is the purpose of using the inversion of control pattern in the Spring Framework?

The Inversion of Control (IoC) pattern in the Spring Framework is used for managing dependencies between objects. Its goal is to separate the creation and binding of objects from their usage, which enhances modularity and testability of the code. In Spring, this is implemented through a container that creates objects and injects the necessary dependencies (Dependency Injection). This allows developers to focus on business logic rather than managing the lifecycle of objects.

Example of dependency injection via constructor:

@Component
public class Service {
    private final Repository repository;

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

    // methods
}

Here, Spring will automatically create a Repository object and pass it to the Service.
