Swap the data elements pointed by Head and Tail pointers. Increment Head and decrement Tail pointers until Head and tail cross each other.

While loop condition is wrong because getting null in doubly linklist is not possible if it has atleast one element

Here is the Java code which I think might work!

public Node reverseDoubLL(Node head){
  Node temp = head;
  temp.prev = temp.next;
  temp.next = null;
  while(head.next!=null){
    Node temp1 = temp;
    head = head.next;
    temp = head;
    temp.prev = temp.next;
    temp.next = temp1;
  }

  return temp;
}
