No,
it's exactly the same as WordUtils.wrap( String, int, String, boolean).
Well, forget interrupt then. Thank you for the tip. I didn't know
WordUtils till now.

This looks vaguely similar to the methods in WordUtils. Possibly it
could be done as an adjustment to one of those, although I don't know
how common a case it is.

Hello all,
building my websites guestbook, i figured out that somebody entered a
big string (exactly: an URL). This blew up my complete layout. HTML
doesn't give any solution on this, you simply can't break up this
stupid long string.
Looking at commons lang i found a lot of join/split-operations, but it
seems that never anybody needed something of a "separate after 20
characters with a blank"-function. Well, i am not sure if ever
somebody REALLY needs this besides me, but you'll never know. So i
decided to let take you a look at my method (attached).
OK, i know it's not the very best method in the world (at least it
midnight and i was at a whiskey tasting this evening), but if somebody
thinks it could be useful to be included in
org.apache.commons.lang.StringUtils i will improve it and would be
glad to contribute "interrupt()" to you. If somebody has a better idea
than this, your comments are welcome.
Let me know.
Having said this, good night.
