Print 2021 one digit per line in reverse order and in vertically order?

[Madjia22]

import java.util.Scanner;
public class STressed
{
public static void main(String[] args)
{
int number = 2021 , Reverse = 0;

while(number !=0)
{
int digit =number%10;

Reverse = Reverse * 10+digit;

}

System.out.println(" Reversed number: " + Reverse);

}
}

import java.util.Scanner;
public class STressed
{
public static void main(String[] args)
{
int number = 2021 , Reverse = 0;
 
while(number !=0)
{
int digit =number%10;
 
Reverse = Reverse * 10+digit;
 
}
 
System.out.println(" Reversed number: " + Reverse);
 
}
}

What's the question? 'number' may need updation.
