但当我们细看一下LinkedList的class定义,就会发现,它并不像是ArrayList的那样具有纯洁的列表精神。 publicclassArrayList<E>extendsAbstractList<E>implementsList<E>,RandomAccess,Cloneable,java.io.Serializable//VSpublicclassLinkedList<E>extendsAbstractSequentialList<E>implementsList<E>,Deque<E>,Cloneable,java.io....

ArrayList和LinkendList不是我们想的那样? Linked是基于双向链表数据结构实现的,存储数据的内存地址是不连续的,是通过指针来定位不连续地址,因此LinkedList不支持随机快速访问,所以LinkedList不能实现RandomAccess接口...LinkedList遍历元素: LinkedList的获取元素的操作和删除元素的操作基本类似,都是分前后半段循环查找...
