What is Inversion of Control (IoC) in Spring Framework

Inversion of Control (IoC) is a design principle where the control of object creation and flow of a program is inverted from the traditional approach. In Spring framework, IoC is implemented through Dependency Injection.

Dependency Injection is a way to provide objects that an object needs (dependencies) instead of having the object create them itself. This allows for loose coupling between components and promotes easier maintenance and testing.

In Spring, IoC container is responsible for managing the lifecycle of objects and creating dependencies. The container creates objects, wires them together, configures them, and manages their complete lifecycle from creation to destruction.

Overall, Inversion of Control in Spring framework helps in creating more modular, flexible, and maintainable applications by decoupling dependencies and handling object lifecycles efficiently.
