In Java, how can I determine if a char array contains a particular character?

Question

Here\'s what I have:

char[] charArray = new char[] {\'h\',\'e\',\'l\',\'l\',\'o\'};

I want to write something to the effect of:

<

From NumberKeyListener source code. This method they use to check if char is contained in defined array of accepted characters:

protected static boolean ok(char[] accept, char c) {
    for (int i = accept.length - 1; i >= 0; i--) {
        if (accept[i] == c) {
            return true;
        }
    }

    return false;
}

It is similar to @ÓscarLópez solution. Might be a bit faster cause of absence of foreach iterator.
