Explain Model, ModelMap and ModelAndView?

The Model interface defines a holder for model attributes. The ModelMap has a similar purpose, with the ability to pass a collection of values. It then treats those values as if they were within a Map. We should note that in Model (ModelMap) we can only store data. We put data in and return a view name.

On the other hand, with the ModelAndView, we return the object itself. We set all the required information, like the data and the view name, in the object we're returning.
