        Scanner in = new Scanner(System.in);
        System.out.println("Enter a String");
        String line = in.nextLine();
        while (true) {
            int space = line.indexOf(' ');
            String word = line.substring(0, space == -1 ? line.length() : space);
            System.out.println(word + " " + word.length() + " " + (word.length() > 1 ? word.substring(word.length() - 1)
                    + word.substring(1, word.length() - 1) + word.substring(0, 1) : word));
            line = line.substring(space + 1);
            if (space == -1) {
                break;
            }
