Answer
It centralizes and manages object creation for consistency and ease.
In large applications, managing object lifecycles and dependencies manually can lead to errors and inconsistencies. Spring Boot uses the Application Context to instantiate and configure beans, ensuring they are properly managed and injected where needed. For instance, in an e-commerce application, the Application Context would automatically instantiate a PaymentService class and inject it into OrderProcessor, reducing boilerplate and error risk.
