that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared to that for the LinkedList implementation.
10. Performance and Time Complexity of ArrayList Operations The performance of ArrayList operations varies from method to method. The methods which do not require moving other elements or list resizing perform best with O(1), whereas other methods perform O(n) in worst cases when they need to ...
ArrayList has O(n) time complexity for arbitrary indices of add/remove, but O(1) for the operation at the end of the list. LinkedList has O(n) time complexity for arbitrary indices of add/remove, but O(1) for operations at end/beginning of the List. Â I use the following code t...
Java provides a convenient sorting mechanism through which ArrayList elements can be arranged in a desired order, enhancing the efficiency of search, retrieval, and manipulation operations. Understanding how to utilize the ArrayList’s sorting functionality is key to optimizing data processing in various...
ArrayList provides constant time for search operation, so it is better to use ArrayList if searching is more frequent operation than add and remove operation. The LinkedList provides constant time for add and remove operations. So it is better to use LinkedList for manipulation. ...

All of the other operations run in linear time (roughly speaking). That includes remove(). So repeated removals of odd numbers will run in quadratic time. If you iterate backwards in MS' array list, after the first removal, nothing needs to be moved, after the second removal one item, ...
