Как влияет удаление элемента из очень большого массива на его производительность?

In Java, arrays have a fixed size, so removing an element from a very large array directly is impossible without creating a new array. Usually, to "remove" an element, a new smaller array is created and all elements except the removed one are copied into it. This operation has a linear complexity of O(n), where n is the size of the array, which can significantly impact performance with large data volumes.

If a data structure like ArrayList is used, removing an element causes all subsequent elements to shift left, which also takes O(n) time in the worst case. Therefore, for frequent removals from large collections, it is better to use data structures with more efficient removal operations, such as LinkedList.
