Henri Yandell commented on LANG-348:
------------------------------------
Given it's likely to be used on small Strings, I'd rather just have an API of:
repeat(String, String, int)
I did testing with join and found that char separates were 10% faster, but
there's no pressing need to add the char overload until requested.
Biggest pain in this - the repeat method is quite an optimized method and you
can't simply splice in a separator. In fact - given the optimization I think
the repeat and removeEnd method will be the best.
> Add StringUtils.repeat with separator

> I would like to have a repeat method with the ability to set a separator:
> public static String repeat(String str, char separatorChar, int repeat)
> Usage scenario: generate insert statements for JDBC preparedstatements:
> assertEquals("?,?,?,?", StringUtils.repeat("?", ',', 4));
> Can this be added to commons-lang?
> Thanks!
