Just another solution to this problem. Though the time complexity remains the same, this code achieves the solution in a single loop.

public Link findKthElementFromEnd(MyLinkedList linkedList, int k)
    {
        Link current = linkedList.getFirst();//current node
        Link currentK = linkedList.getFirst();//node at index k

        int counter = 0;

        while(current.getNext()!=null)
        {
            counter++;

            if(counter>=k)
            {
                currentK = currentK.getNext();
            }

            current = current.getNext();
        }

        //reached end
        return currentK;
    }
