you can use System.out.printf("%03d", valueName);

what happens is that any value that will be printed would be at least 3 numbers in length and it will print preceding 0s.

int lengthOfBigger = String.valueOf(biggerNumber).length();
String pattern = "%0" + lengthOfBigger + "d";

String smallerNumberPadded = String.format(pattern, smallerNumber);

Taken mostly from this question

EDIT:

For just spaces change pattern to

String pattern = "% " + lengthOfBigger + "d";
