Function argument and return value does look incorrect-ResponseEntity

Posted 14 May 2018 - 06:07 AM

I have such problem with ResponseEntity. The function returns such statement:

public ResponseEntity<User> .... //this is declaration of function



And function doesn't return type User instead some thing:

return new ResponseEntity<>(HttpStatus.NOT_FOUND); //This is return value of function 



Maybe there is a problem:

<>



What this above statement does mean?


1.
What does mean and what the difference is between:

ResponseEntity<User>


and

ResponseEntity<>


2.
Compare secound point with my first statement:

Another example is:
Function does begin the same as previous:

public ResponseEntity<User> saveUser(parameters)


but the return value is

 return new ResponseEntity<>(savedUser, HttpStatus.NOT_FOUND);



I can't figure it out when comparing with:

return new ResponseEntity<>(HttpStatus.NOT_FOUND);


Can it be used both with function returning ResponseEntity<User>
Maybe an author made a mistake?
This is the theory from the book. But I would be grateful for some explanation. Next I want do some my practice effort to be better.
Regards

EDIT:
These are detection statements does Rest statement worked properly or not
