I have \"Hello World\" kept in a String variable named hi.

I need to print it, but reversed.

How can I do this? I understand there

    public static String reverseIt(String source) {
        int i, len = source.length();
        StringBuilder dest = new StringBuilder(len);
    
        for (i = (len - 1); i >= 0; i--){
            dest.append(source.charAt(i));
        }
    
        return dest.toString();
    }
