Lets say I have a String var which can contain values of different lengths e.g.
"aaa" or "bb bb bb".

I want to print them out with System.out.println right-justified with a field width
of 12 chars. If necessary this field should be left padded with blanks.
For the samples above the output should be e.g.:

" aaa"
and
" bb bb bb"

How can I implement this right-justified, blank padded, fixed-width filed output in Java?

What if the field is bigger than 12 chars?

Anyway Jakarta commons contains a lot of very useful stuff, including
a lot of StringUtils
very convenient methods, including leftpad, etc.

If you want don't want to use Jakarta commons for this, you may write
a helper method
somewhere in your project.

The following may help (not tested):

private static final String PAD = " ";

final String s ="aa aaa aa";
System.out.println( PAD.substring( Math.min(PAD.length(),
s.length())) + s);
