Question

Using jGrasp and the Software Development Kit, write a program in response to the following prompt: Write a method, reverseDigit, that takes an integer as a parameter and returns the number with its digits reversed. For example, the value of reverseDigit(12345) is 54321. Also, write a program to test your method. Submit your compiled Java code for this assignment, compress the .java file into a single .zip file. For additional details, refer to the Programming Problems Rubric in the Assignment Guidelines and Rubrics folder.

Explanation / Answer

Here is the java code

import java.util.Scanner;

class ReverseNumber
{
   ////////Static method which performs the reverse operation
   public static int reverseIt(int n)
   {
      int reverse=0;
      while( n != 0 )
         {
             reverse = reverse * 10;
             reverse = reverse + n%10;   // Divide n by 10 contineously untill n becomes less n becomes less zero and on each itertion
                                          // Obtain its modulus to get digits at different decimal places
             n = n/10;           
         }
         return reverse;

   }

   public static void main(String args[])
   {
      int n;

      System.out.println("Enter the number to reverse");
      Scanner in = new Scanner(System.in);
      n = in.nextInt();

     
      System.out.println("Reverse of entered number is "+reverseIt(n));
   }
}

output
