Modify the above program to complete the same task by replacing the array with ArrayList so that the user does not need to specify the input length at first. The recursion method's first argument should also be changed to ArrayList. The user input ends up with -1 and -1 is not counted as the elements of ArrayList. REQUIREMENTS ● . . ● ● The user input is always correct (input verification is not required). Your code must use recursion and ArrayList. The recursion method int addition (ArrayList<Integer> al, int start Index) is a recursion one whose arguments are an integer ArrayList and an integer, the return value is an integer. The main method prompts the user to enter the elements of the ArrayList myArrayList, calculates the addition of all elements of the array by calling the method addition (myArrayList, 0), displays the result as the following examples. Your code must work exactly like the following example (the text in bold indicates the user input). Example of the program output: Example 1: The elements of your array are: 123456-1 The addition of 1, 2, 3, 4, 5, 6 is 21. Example 2: The elements of your array are: 25 8 12 67 -1 The addition of 2, 5, 8, 12, 67 is 94.
