In an ArrayList, if an item is added using Insert method like below- al.Insert(2, "item") What will happen to the existing item at index 2?

It slides to the next position at index 3.

It will shift to the next index of that ArrayList.

Please follow the given example below

ArrayList a1 = new ArrayList();
a1.Add(“abc”);
a1.Add(“aa”);
a1.Add(“baba”);

//before inserting new element
Console.WriteLine(a1[2]);

//adding new element at 2nd index
a1.Insert(2, “item”);

//after added
Console.WriteLine(a1[2]);
Console.WriteLine(a1[3]);
//“baba” is shifted at index 3 now

Console.ReadLine();

It shifted records to other index after index 2, That means it shift 2 index record to 3 and 3 to 4 and so on.

will be at index 3 position

After you add item to position 2, it will move existing item to position 3.

item at position 2 will shift down
