node.java

真的很麻烦也

class Node 
{
  private Node prev, next;	
  private Object element;	
  public Node(Node newPrev, Node newNext, Object elem) 
  {
    prev = newPrev;
    next = newNext;
    element = elem;
  }
  public Object element() 
  {    
    return element;
  }
  public Node getNext() 
  {
  	return next;
  }
  public Node getPrev() 
  { 
  	return prev; 
  }
  public void setNext(Node newNext) 
  { 
  	next = newNext; 
  }
  public void setPrev(Node newPrev) 
  {
  	prev = newPrev; 
  }
  public void setElement(Object newElement) 
  {
  	element = newElement; 
  }
}
