E poll() 删除并返回head。E remove()相同,可能抛出异常,所以忽略booleanoffer(E e),调用的是add(),添加元素作为tail(也就是last) Dequeue操作 E peekFirst(),E peekLast() E pollFirst(),E pollLast()booleanofferFirst(E e),booleanofferLast(E e) ...

删除(remove/pop)方法 LinkedList类常用方法测试: 简介 LinkedList是一个实现了List接口和Deque接口的双端链表。 LinkedList底层的链表结构使它支持高效的插入和删除操作,另外它实现了Deque接口,使得LinkedList类也具有队列的特性; LinkedList不是线程安全的,如果想使LinkedList变成线程安全的,可以调用静态类Collections类...
