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

Object having a reference of one variable store in stack whereas "E" is created in a heap don't have a reference variable

Object is a class and E is a generic type parameter . And Iterator class alwayes return Object so to fix this problem, you need to call it. For example

import java.util.ArrayList;

import java.util.Iterator;

class list {

   ArrayList list = new ArrayList();

  

   public E next() {

     Iterator i = list.iterator();

     return (E)i.next();

   }

}

    

public class TestProgram {

   public static void main(String[] args) {

     list list = new list();

     list.list.add("A");

     System.out.println(list.next());

   }

    

}
