title: What is node, node.next and node.next.next in linked-list.?
body: <p>I am just curious about node . node.next and node.next. Until now we have read that node has two part in which it store data and address of next node(node.next) then whats about node.next.next. ? Where the address of node.next.next will be stored. I just implemented node.next.next to delete a number from the end of list. Its working well. Butt i don't know about node.next.next?? please help me in understanding of concept of nodes.
  Here is code in which i implemented node.next.next.</p>
  
  <pre><code>public void del_`enter code here`end(){
          Node temp = head;
          while(temp.next.next!=null ){
              temp= temp.next;
          }
          temp.next= null;
  
  }
  </code></pre>
