SLinkedList and Node in Java

To start with, yes, this is for an assignment in class, but my lack of understanding on how it operates is higher than I want it to be.
We were given 3 classes, they are the following:
SLinkedList.java
package chapter3.linkedList;

public class SLinkedList<V> {
    // instance variables.  Add the tail reference.

        head = null;
        tail = null;
        size = 0;
    }  // end constructor of a SLinkedList

    // method to add nodes to the list.  Storage space for the node
    // is already allocated in the calling method
    public void addFirst (Node<V> node) {
        // set the tail only if this is the very first node
        if (tail == null)
            tail = node;
        node.setNext (head);    // make next of the new node refer to the head
        head = node;            // give head a new value

        // change our size
        size++;
    }  // end method addFirst

    // addAfter - add new node after current node, checking to see if we are at the tail
    public void addAfter (Node<V>currentNode, Node<V>newNode) {
        if (currentNode == tail)
            tail = newNode;

        currentNode.setNext (newNode);
