LinkedList vs ArrayList single insert and insert in a loop in the middle?

Question

Java

I read that a one-time insertion into the middle is the same in both cases, but if you insert many elements into the middle in a loop, then the arraylist is slower than linkedList, but when checking through measureTimeMillis {}, the time is approximately the same shows which method you need to insert the elements to see the difference ?

Answer 1

Throw a million elements into the list in advance, and then insert the elements at the beginning - the effect will be immediately visible
