Minor Description
This is a patch to commons.lang to add the following two methods
to StringUtils
public static String join(Object[] array, char separator)
public static String join(Iterator iterator, char separator)
They're equal to the ..., String separator) methods but take
a char as second parameter.
I also took a look at the other join methods and enhanced them for the
separator == null case.
The test case for join has been extended for test cases of the new
methods, tests for the null separator and some test for joining
an empty array / collection object.
Please apply.
