<p>Returns padding using the specified delimiter repeated to a given length.</p> <pre> StringUtils.repeat('e', 0) = "" StringUtils.repeat('e', 3) = "eee" StringUtils.repeat('e', -2) = "" </pre> <p>Note: this method doesn't not support padding with <a href="http://www.unicode.org/glossary/#supplementary_character">Unicode Supplementary Characters</a> as they require a pair of char s to be represented.
