descendingIterator() returns an iterator over the elements in Refer post How Linked List class works internally in Java to know more about internal working of LinkedList.ДЈ- One more difference is that LinkedList implementation provides a descendingIterator() which comes from.Refer post How ArrayList works internally in Java to know more about internal working of ArrayList.Where as in LinkedList a new node has to be created and references for NextДЄnd Prev are to be adjusted to accommodate the new Node. Will work faster because it already has an initial capacity and just need to add that element at the index What it means is that if elements are added at the last every time and capacity is not breached then ArrayList Is no provision of initial capacity or default capacity. Just provides one constructor LinkedList() which constructs an empty list.

LinkedList is implemented using a doubly linked list concept where asДЄrrayList internally uses an array of Objects which can be resized dynamically.Дў- ArrayList class provides a constructor ArrayList(int initialCapacity) even if the default constructorДЄrrayList() is used an empty list is constructed with an initial capacity of ten.

ArrayList Vs LinkedList in JavaДЎ- If we have to list the differences between the LinkedList and ArrayList in Java, first difference is in the implemenation itself. So let's see some of the differences between ArrayList and LinkedList in Java, it will help you in making an informed choice when to use ArrayList and when a LinkedList. In most of the cases we do use ArrayList and it works very well but there are some use cases where using LinkedList may be a better choice. Interface (LinkedList also implement Deque interface though). In Java collections framework ArrayList and LinkedList are two different implementations of List
