As it stands, you''re constructing this String object on top of a char array, just so that you can grab the char array back out of it.)Of course, that''s rather error-prone. share|improve this answer answered Sep 9 '10 at 7:11 DigitalRoss 104k12178258 1 +1 for suggesting a reasonable solution to the problem. –Billy ONeal Sep 9 '10 at 7:14 Am I interrupting my husband's parenting?

What does "M.C." in "M.C.
