Hi all, I am trying to properly code a moveUp() method that will move an item above another in a queue. This method is inside my QueueList class which extends LinkedList. What I am trying to have it do is the method will take a parameter int of the index for which to move higher. Having issues with my logic here so I was hoping someone could work out the kinks. I have it coded like so:

public void moveUp(int index) {
		Node current = head;
		Node previous = null;
		Node follow = null;
		int count = -1;
		for (Node i = head; i != null && count < index; i = i.next) {
			previous = current;
			follow = current;
			current = current.next;
		current = follow;
		current.next = previous.next;
