<p> <span>对于插入，索引表示在插入发生之后树的<i>最终</i>状态。</span> <span>由于索引必须按顺序指定，所以最自然的处理方法是从最低索引开始进行插入，并以最高的方式工作。</span> <span>累加一个<code>Integer</code>对象，指定插入位置，然后将Vector转换为<code>int</code>的数组以创建事件。</span> <span>当postition-index等于零时，节点将被插入列表的开头。</span> <span>当位置索引等于列表的大小时，节点在列表的末尾（附加到）处被“插入”。</span> </p>

<p> <span>对于删除，索引代表树的<i>初始</i>状态，在删除发生之前。</span> <span>由于索引必须按顺序指定，最自然的处理方法是使用删除计数器。</span> <span>首先将计数器初始化为零，然后通过列表从最低到最高开始工作。</span> <span>每次删除时，将删除计数器的当前值添加到发生删除的索引位置，并使用<code>addElement()</code>将结果附加到“删除位置向量”。</span> <span>然后递增删除计数器。</span> <span>因此，存储在Vector中的索引位置反映了所有以前删除的效果，因此它们表示每个对象在初始树中的位置。</span> <span>（你也可以开始在最高指数，对最低工作恢复，积累的删除，位置的载体，当您去使用<code>insertElementAt(Integer, 0)</code> ）。但是你产生初始位置的矢量，你再需要的向量转换<code>Integer</code>对象到一个<code>int</code>的数组来创建事件。</span> </p>
