Memory Overhead: ArrayList maintains indexes and element data while
ArrayList class has set(),
Reason: ArrayList maintains an index based system for its elements as it uses array data structure implicitly which makes it faster for searching an element in the list.
In my tests LinkedList came out faster, with linked LinkedList coming in around 50,000 NS and ArrayList coming in at around 90,000 NS… give or take.
Note: The sizes shown for the ArrayList lines are for trimmed lists- In practice,
It's easier to modify a linked list than ArrayList, especially if you are adding
while they are O(n) for ArrayList.
DynamicIntArray, btw, is a custom ArrayList implementation holding Int(primitive type)
It's an inner type, which emulates an ArrayList but actually directly references the passed array and makes it"write through"(modifications are reflected in the array).
While in ArrayList, if the array is the full i. e worst case, there is an extra cost of resizing array and copying elements to the new array, which makes runtime of add operation in ArrayList O(n), otherwise it is O(1).
there will be not memory wasted(as in ArrayList with the difference between the capacity and actual number of elements), and there would be
Thus far, nobody seems to have addressed the memory footprint of each of these lists besides the general consensus that a LinkedList is"lots more" than an ArrayList so I did some number crunching to demonstrate exactly how much both lists take up for N null references.
