我想在array/arraylist中单独存储一个数字，并按给定的顺序写出它们。有什么建议我做错了什么？

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

class Main {

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    List<Integer> digits = new ArrayList<Integer>();

    int number = scanner.nextInt();

    while (number > 0) {
        int digit = number % 10; // Store digit in a variable
        number = number/10;
        digits.add(digit); // Add digit to the list
    }
    System.out.println(digits.get(1, 0)); //given the scanned number eg. 23, i'd like to write out 32
}
}
