< p > 基于邻接表实现图的代码如下所示。细心的同学可能注意到，< strong > 我们在邻接表中使用 < code > Vertex< / code > 结点类来表示顶点< / strong > ，这样做的原因是：< / p >
< ul >
< li > 如果我们选择通过顶点值来区分不同顶点，那么值重复的顶点将无法被区分。< / li >
< li > 如果类似邻接矩阵那样，使用顶点列表索引来区分不同顶点。那么，假设我们想要删除索引为 < span class = "arithmatex" > \(i\)< / span > 的顶点，则需要遍历整个邻接表，将其中 < span class = "arithmatex" > \(> i\)< / span > 的索引全部执行 < span class = "arithmatex" > \(-1\)< / span > ，这样操作效率太低。< / li >
< li > 因此我们考虑引入顶点类 < code > Vertex< / code > ，使得每个顶点都是唯一的对象，此时删除顶点时就无需改动其余顶点了。< / li >
