If you want to fix the long if chain you can do something like this:

if (anyOf(R2D2, "AaEeIiOoUuYy".toCharArray())

and later have:

private static boolean anyOf(char in, char[] items) {
    for (int i = 0; i < items.length; i++) {
        if (in == items[i])
            return true;
    }
    return false;
}
