How to right-align numbers with DecimalFormat

Question

I want this form of output:
(0 is really a space, but this forum doesn't allow the leading spaces.)
0023
0005
0324
0011
4972
0008
0055
What should be the pattern givent to the DecimalFormat constructor?
Or, other way around?

Answer 1

example :
    public static String rightAlign(int totalLength, int number)
        String text = String.valueOf(number);
        int remainLength = totalLength - text.length();
        if (remainLength > 0)
            char [] blank = new char [remainLength];
            Arrays.fill(blank, ' ');
            text = String.valueOf(blank) + text;
        return text;
    }
