你如何遍历链表的末尾？

Question

有人能解释一下

是什么吗？

current = current.getnext();

从下面的代码中真正意味着什么？

public void add(Object data)
// post: appends the specified element to the end of this list.
{
    Node temp = new Node(data);
    Node current = head;
    // starting at the head node, crawl to the end of the list
    while(current.getNext() != null)
    {
        current = current.getNext();
    }
    // the last node's "next" reference set to our new node
    current.setNext(temp);
    listCount++;// increment the number of elements variable
}
