public class SplitNumber
{
 public static void main(String[] args)
 {
  int num, temp, factor = 1;
  Scanner sc = new Scanner(System.in);
  System.out.println("Enter a number: ");
  num = sc.nextInt();
  temp = num;
  while (temp != 0) {
   temp = temp / 10;
   factor = factor * 10;
  }
  System.out.print("Each digits of given number are: ");
  while (factor > 1) {
   factor = factor / 10;
   System.out.print((num / factor) + " ");
   num = num % factor;
  }
 }
}

Output:
