IOC

Key Concepts of IoC

1. Dependency Injection (DI):

   • A common implementation of IoC where dependencies are “injected” into a class rather than the class creating them itself.
   • Dependencies can be injected via:
     • Constructor injection
     • Setter injection
     • Interface injection

2. Control Delegation:

   • Instead of the program controlling the flow of execution, the control is handed over to a framework or container.

3. Benefits:

   • Improved modularity and separation of concerns.
   • Easier testing (mocking dependencies).
   • Reduced boilerplate code.
   • Better scalability and maintainability.
