Henri Yandell commented on LANG-330:
------------------------------------
Also tempted to consider for repeat(...),
Downside of this is that it potentially means duplicating the entire API for each method.
9 methods for join, 1 method for repeat.
Still - not sounding like enough yet to warrant the painfully named AppendableUtils.
> Add StringBufferUtils or overload StringUtils methods

>
> There's especially one group of methods you should overload with StringBuffer (or Appendable
in a special JDK5 Class?):
> StringUtils.join
> It should take a StringBuffer (/Appendable) as first Argument to which the Strings will
be added.
> Usage Example:
> StringBuffer sql = new StringBuffer("SELECT * FROM foo WHERE bar IN (");
> StringUtils.join(sql, bars, ", ");
> sql.append(") AND bar NOT IN (");
> StringUtils.join(sql, noBars, ", ");
> sql.append(");");
