Yes.

The default behavior of add is to add it to the end of the ArrayList, however if you want, you can indicate the exact index where you want to insert the element.

Code Example

1. ArrayList nums = new ArrayList();
2.  
3. nums.add(1);
4. nums.add(2);
5. nums.add(3);
6. nums.add(0, 999); // add number 999 to position 0 in the ArrayList
7. nums.add(4);
8. nums.add(5);
9.  
10. println(nums);
11. 
    
12. exit();
