ArrayList with integers and user input

So I have a school assignment that I am stuck on and would like some guidance on how to approach it. The task is:

The purpose of this lab is to manipulate an ArrayList of integers. The assignment is to write a program that: 1. Declares an ArrayList of integers. 2. Implements the following methods:  A method that displays a menu. The menu should be displayed after each completed menu selection. 1. Add elements 2. Add an element at a specific index 3. Remove an element at specific index 4. Show min, max, sum and average 5. Search 6. Exit

So I already have the code here

import java.util.Scanner; public class ArrayList { static int count; static Scanner kb = new Scanner(System.in); public static void main() { int item=0; ArrayList numArray = new ArrayList(); count=0; while (item !=6) { menu(); item=kb.nextInt(); if (item==1) addElements(numArray); //else if (item==2) //printArray(numArray); } System.out.println("Goodby!"); } public static void menu() { System.out.println("1. Add Elements"); System.out.println("2. Add an element at a specific index"); System.out.println("3. Remove an element at a specific index"); System.out.println("4. Show min, max, sum and average"); System.out.println("5. Search"); System.out.println("6. Exit"); System.out.print(": "); } public static void addElements(ArrayList arr) { count=0; int num; System.out.print("Enter integer values to fill the arrayList -vevalue to stop: "); do { num = kb.nextInt(); if (num >=0) { arr.add(count); count++; } } while (num > 0); } 

So basically when you input 1 in the console, itll prompt you to add integers to the empty arraylist I established in the beginning. Im just having trouble with the first part alone with the syntax on how to get the user input to be added to the array list.
