ArrayList是Java中的一个动态数组类,它允许我们在运行时动态地添加或删除元素。我们可以先将数组转换为ArrayList,然后使用add()方法来添加新元素,最后再将ArrayList转换回数组。 // 创建一个数组int[]arr={1,2,3,4,5};// 将数组转换为ArrayListList<Integer>list=newArrayList<>();for(inti:arr){list.add(i)...
* @param e element to be appended to this list * @return {@code true} (as specified by {@link Collection#add}) */ public boolean add(E e) { linkLast(e); return true; } /** * Links e as last element. */ void linkLast(E e) { final Node<E> l = last; final Node<E> ...
就是ArrayList里面的elementData数组里面最后一个元素后面进行添加一个。 LinkList 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。
