/********* NumberParser.java ********/

import java.util.Scanner;

public class NumberParser {

   public static void main(String[] args) {

       /*
       * Declaring variables
       */
       int number, first, second;

       /*
       * Creating an Scanner class object which is used to get the inputs
       * entered by the user
       */
       Scanner sc = new Scanner(System.in);

       // Getting the input entered by the user
       System.out.print("Enter a two digit number :");
       number = sc.nextInt();

       // Finding the first and second digit
       first = number % 10;
       second = number / 10;

       // Displaying the output
       System.out.println(second + "<-->" + first);

   }
