Question
What is the difference between iterator access and index access
Answers
Index based access allow access of the element directly on the basis of index. The cursor of the datastructure can directly goto the 'n' location and get the element. It does not traverse through n-1 elements.

In Iterator based access, the cursor has to traverse through each element to get the desired element.So to reach the 'n'th element it need to traverse through n-1 elements.

Insertion,updation or deletion will be faster for iterator based access if the operations are performed on elements present in between the datastructure.

Insertion,updation or deletion will be faster for index based access if the operations are performed on elements present at last of the datastructure.

Traversal or search in index based datastructure is faster.

ArrayList is index access and LinkedList is iterator access.   Your Comment
