Question

I need help with this Java Problem as described in the image below:

import java.util.ArrayList;
import java.util.Scanner;

public class ArrayListADT {
   public static void printArrayList(ArrayList<Integer> numsList) {
      int i;

      for (i = 0; i < numsList.size(); ++i) {
         System.out.print(numsList.get(i));
         System.out.print(" ");
      }

      System.out.println("");
   }

   public static void main(String [] args) {
      Scanner scnr = new Scanner(System.in);
      ArrayList<Integer> numsList = new ArrayList<Integer>();
      int userInput;
      int i;

      for (i = 0; i < 3; ++i) {
         userInput = scnr.nextInt();
         numsList.add(userInput);
      }

      /* Your solution goes here  */

      printArrayList(numsList);
   }
}

Modify the existing ArrayLists's contents, by erasing the second element, then inserting 100 and 102 in the shown locations. Use
ArrayList's remove() and add() only. Sample output of below program with input 101 200 103:
100 101 102 103
