The DI ensures that all the components and services of the application are not connected through code the IoC container does that job. The Spring container forms the basis of the entire framework and uses the DI to manage application components by creating objects, wiring and configuring them and regulating the overall life. When the application is run, the components and services described would be loosely coupled by required classes in the IoC container. The DI states that we do not create objects manually, but describe the process of their creation instead. You are required to have a thorough understanding of both these terms so that you can explain them clearly.Įxample: 'IoC gives objects dependencies rather than creating or looking for dependent objects. Spring uses a special design principle called the inversion of control (IoC), which manages wiring dependencies and the dependency injection is one of its aspects.
