Notes

In Apex, the set(index, listElement) method is used to update the element at a specified index in a list. The index parameter represents the position where you want to update the element, and the listElement parameter is the new value you want to set at that index.

Here's an example:

List<Integer> numberList = new List<Integer>{1, 2, 3, 4, 5};

System.debug('Original List: ' + numberList);

numberList.set(2, 99);

System.debug('List after update: ' + numberList);

Output:

Original List: (1, 2, 3, 4, 5)

List after update: (1, 2, 99, 4, 5)
