这使得LinkedList删除元素的操作变得``高效,因为同样只需要更改几个点。不过,列表越长,到达需要删除的元素所需的时间就越长,因为我们无法通过索引访问元素。 参考连接: https://stackabuse.com/difference-between-arraylist-and-linkedlist-in-java-code-and-performance/#performancecomparison 上一篇junit的使用 本文...
插入数据和删除数据时,linkedlist只需要O(1),会非常快。 LinkedList需要更多的内存,因为ArrayList的每个索引的位置是实际的数据,而LinkedList中每个node储存的是previous 和 next 的位置。 Array is similar with ArrayList, but it is synchronized. Array and ArrayList require space as more elements are added. Arr...
