Returns padding using the specified delimiter repeated
to a given length.
StringUtils.padding(0, 'e') = ""
StringUtils.padding(3, 'e') = "eee"
StringUtils.padding(-2, 'e') = IndexOutOfBoundsException
Note: this method doesn't not support padding with
Unicode Supplementary Characters
as they require a pair of char
s to be represented.
If you are needing to support full I18N of your applications
consider using
#repeat(String,int) instead.
