Notes

If you want to add all elements from another list to a specific index in the target list, you can use the addAll(index, listToAdd) method.

Here's an example:

List<Integer> firstList = new List<Integer>{1, 2, 3};
List<Integer> secondList = new List<Integer>{4, 5, 6};

firstList.addAll(secondList);

System.debug('Updated List: ' + firstList);

Output: Updated List: (1, 2, 3, 4, 5, 6)
