What is the difference between ResponseEntity<?> and ResponseEntity<Object> and ResponseEntity<MyCustomClass>

Right now I need my controller to return 2 different type of Object based on business logic , So my question is should i use

ResponseEntity <?>

or should I use:

ResponseEntity <Object>

What are the difference between this return types and why should I use them?

Does it make any cahnges to JSON returned by Spring controller?

I'm asking about return types not input parameter.

I use Spring MVC 4.
