Question

if you have to add or delete the elements at the beginning of a list, should you use myarraylist or mylinkedlist?

Answer 1

For frequent additions or deletions at the beginning of a list, LinkedList is more efficient than ArrayList as it allows constant-time operations without shifting elements.

Step-by-step explanation:

If you need to add or delete elements at the beginning of a list often, a LinkedList would be the better choice. This is because LinkedLists are designed with nodes linked to each other, which allows for constant-time insertions and deletions from the beginning of the list without the need to shift other elements. In contrast, an ArrayList requires shifting all subsequent elements when adding or removing an element at the beginning, which can be inefficient for large lists or frequent operations.
