WebAnswer (1 of 12): There's a couple of misconceptions here. Firstly just because something is O(n) doesn't mean we're good. The actual time taken to re-allocate and copy an array might still be a problem. O(n) just means asymptotically linear. It might be 0.000001s x n and therefore the case n=1,0...

WebJun 5, 2024 · Arrays are limited to a size to a signed 32-bit number. This is a historical restriction which is hard to fix to allow signed long sizes unfortunately. The maximum signed int value is 2^31-1. However the size of the array has to be a power of two (due to the way HashMap works) and this is one too few, so the largest power 2 it can be is 2^30.

WebArrayList is a class of Java Collection framework. It uses a dynamic array for storing the objects. It is much similar to Array, but there is no size limit in it.
