1) Iterator is an Interface. 2) It's sole purpose is to iterate not save value. POJO's have getters and setters.

Iterator traverse only in forward direction and you cannot get the index of an element/object. So no point of having a get method in it.

Let's simplify Coding, It's a great Fun.

iterator is meant for sequential traversal of the collection hence it does not contain get() method.Because get() method means direct access of element in a list.

To get any element in a collection using index you can directly use get method provided in Collection. To avoid redundancy they have not provided it in Iterator. And also iterator is only for traversing through elements in a collection sequentially.

Because an iterator generally points to a single instance in a collection. Iterable implies that one may obtain an iterator from an object to traverse over its elements - and there's no need to iterate over a single instance, which is what an iterator represents.
