Need help in Java char[]...

Okay guys... I have a char[] suposely made of A's, B's and C's...

If I find a character that isn't one of those, I want it to throw an exception and leave.

how do I do it?

char[] zong = {A,L,C,B,}

for (int k = 0; k < zong.length; k++ ) {
if ((zong[k] != A) && (zong[k] != B) && (zong[k] != C)) {
throw new Exception("exit");
}
}

Is this it?

thanks, /prog/


case takeWhile (`elem` "ABC") zong of
    [] -> zong
    _  -> error "error"
