注释:remove(int index)方法用于删除List中特定位置的元素。 步骤5:遍历List这些元素 接下来,我们使用增强for循环遍历List中的元素并打印出来。 // 遍历ArrayListSystem.out.println("ArrayList Elements: ");for(intnum:arrayList){System.out.println(num);}// 遍历LinkedListSystem.out.println("LinkedList Elements...
因此在最后删除或插入将给我最好的性能(如 N ~ M),而在开始时删除或插入将是最差的(如 N ~ 1)。 现在是大小为“M”的 LisnkedList:因为我们不能直接到达 LinkedList 中的第 N 个元素,要访问第 N 个元素,我们必须遍历 N 个元素,所以在 LinkedList 中的搜索比 ArrayList 更昂贵……但是删除并且在 Linke...

remove(E e)是 remove 见到的第一个这个元素,那么 ArrayList 要先找到这个元素,这个过程是 O(n),然后移除后还要往前移一位,这个更是 O(n),总的还是 O(n); LinkedList 也是要先找,这个过程是 O(n),然后移走,这个过程是 O(1),总的是 O(n). ...

When our frequently used operation is adding or removing elements in the middle of the List, LinkedList is the best class to use. Why?Because we don’t need to do more shifts to add or remove elements at the middle of the list. Please refer “How Insertion works in J Java LinkedList?
