public class PrintStringInReverse {

    public static void printReverse(String s) {
        if(!s.isEmpty()) {
            printReverse(s.substring(1));
            System.out.print(s.charAt(0));
        }
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter a string: ");
        String s = in.nextLine();
        printReverse(s);
        System.out.println();
