title: Java: alternative to LinkedList or int pointer data structure
body: <p>Since LinkedList is a nightmare in terms of memory overhead and also slower when iterating elements, I would like to have something like int poiter data structure.</p>
  
  <p>So I have a list of ints and I form it by inserting elements at the beginning-middle. When the list is ready, I iterate it in a one-by-one fashion from the left. That is my problem constraint.</p>
