What's the difference between Object and "E"?

I'm trying to write an Iterator class for a LinkedList class that I wrote.
One of the methods is "public E next()"
I try to return an "E" but eclipse says "cannot convert from Object to E".
How do I fix this?

Object is a class where as E is nothing but Generic Argument, While writing Generic Classes we will use type E.
