4 Here is code to reverse a positive integer number, that is we input 123 and the computer will output 321. Please check whether this code is correct; if not, please correct it import java.util Scanner: public class ReverseNumber I Reverses the digits of an integer mathematically public static void main(Stringll args) int number, lastDigit, reverse 0; Scanner scan-new Scanner(System.in) System.out.prini"Enter a positive integer: ": a -scan nextint0 do reverse (reverse 10) + a b-b9610; a-a, 10; while (ac0); System.out printin"That mumber reversed is"+reverse): 6/9

Explanation / Answer

import java.util.Scanner;

class ReverseNumberWhile

{

   public static void main(String args[])

   {

      int num=0;

      int reversenum =0;

      System.out.println("Input your number and press enter: ");

      //This statement will capture the user input

      Scanner in = new Scanner(System.in);

      //Captured input would be stored in number num

      num = in.nextInt();

      //While Loop: Logic to find out the reverse number

      while( num != 0 )

      {

          reversenum = reversenum * 10;

          reversenum = reversenum + num%10;

          num = num/10;

      }

      System.out.println("Reverse of input number is: "+reversenum);

   }

}
