Add input into list

Question

I'm trying to add user's input into list and then show it in reverse order. The elements are added until the user enters 0. Here's my code:

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

public class InputInArrrayList{
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        int a = s.nextInt();
        List<Integer> myList = new ArrayList<>();
        while(a > 0) {
            myList.add(a);
            if (a == 0){
                break;
            }
        }
        Collections.reverse(myList);
        System.out.println(myList);
    }
}

But the loop doesn't break when it's 0. Instead, it throws OutOfMemoryError: Java Heap space. What am I doing wrong?

Answer 1

at least one a >= 0 needed for break to execute:

   while(a >= 0) {
        myList.add(a);
        if (a == 0){
            break;
        }
    }
