【问题描述】：

我在一本书中遇到了这个单链表实现。但是，我不明白一些说法。我对每个陈述的问题都针对每个陈述列出。

1 class Node {
2   Node next = null;  //Is this a constructor?
3   int data;
4   public Node(int d) { data = d; }
5   void appendToTail(int d) {
6     Node end = new Node(d);
7     Node n = this;//Why is "this" keyword used here?  What does this do?
8     while (n.next != null) { n = n.next; }//Where does "next" member come from?
9     n.next = end;
10   } 
11 }

【解决方案1】：

2 Node next = null; //Is this a constructor? NO it is not. 
4 public Node(int d) { data = d; } //This is constructor
7 Node n = this; //The this keyword refers to the current instance of the class
8 while (n.next != null) { n = n.next; } //Learn Linked list
