publicbooleanadd(E e){ linkLast(e);returntrue; } 也总是返回true。在linkLast中实现的是链表 List内部实现的双链表,lsat是最末位的元素,linkLast把元素连接到末位。 /** * Links e as last element.链接e作为最后一个元素。 */voidlinkLast(E e){finalNode<E> l = last;finalNode<E> newNode =ne...
Node(Node<E> prev, E element, Node<E>next) {this.item =element;this.next =next;this.prev =prev; } } LinkedList 中定义了3个变量,一个代表当前列表的元素个数,另外两个变量指向链表的头部和尾部。以及它的父类 AbstractList 中的 modCount 变量,每次对链表的增删改操作都会使它加1。 transientintsi...

LinkedList 继承自 AbstractSequentialList,又实现了 List、Deque、Cloneable、Serializable等接口. AbstractSequentialList相较于AbstractList(ArrayList的父类),只支持次序访问,而不支持随机访问,因为它的get(int index) ,set(int index, E element), add(int index, E element), remove(int index) 都是基于迭代器实...
