Doubly-linked list implementation of the List and Deque interfaces. Implements all optional list operations, and permits all elements (includingnull). 2. set和get函数 publicE set(intindex, E element) { checkElementIndex(index); Node<E> x =node(index); E oldVal=x.item; x.item=element;ret...
LinkedList中的很多方法其实都来自于List接口,所以它的很多方法与ArrayList是一样的。但由于其自身特点,...

1. LinkedList is doubly linked, so it takes up more space and cannot hold as many elements as ArrayList. 2. Insertion, ArrayList is faster, in the same level, ArrayList may be two times faster, not that obvious with few elements (<100,000) ...
