Reverse a Number Program in Java

In this tutorial I would like to share with you a simple program that I wrote in Java that will ask the user to enter a number in integer format then it will reverse the arrangement of numbers. The code is very straight forward to follow and understand it will serve as a basis for anyone that are new in Java programming.

Sample Output of Our Program

Program Listing

import java.lang.*;

import java.util.Scanner;

class rev

{

public static void main(String args[])

{

  Scanner in = new Scanner(System.in);

   char a;

do

 {

    int num1=0,r=0;

    int solve_value=0;

 System.out.println("==============================================");

 System.out.println("||    <<< REVERSE A NUMBER PROGRAM >>>      ||");

 System.out.println("==============================================");

     System.out.print("\n");

     System.out.print("Enter a Number :=>");

          num1 = in.nextInt();

     System.out.println("\n");

 System.out.println("=======================");

 System.out.println("||  DISPLAY RESULT   ||");

 System.out.println("=======================");

 System.out.println("\n");

 System.out.println("Original Number Arrangement :=> " +num1 +".");

while(num1>0)

  {

r=num1%10;

solve_value=(solve_value*10)+r;

num1=num1/10;

          }

       System.out.println("Reverse of number result    :=> " +solve_value +".");

       System.out.println("\n");

       System.out.print(" Do you Want To Continue(Y/N) :=> ");

       a=in.next().charAt(0);

   } while(a=='Y'|| a=='y');

       System.out.println("\n");

       System.out.println("\t ===== END OF PROGRAM ======");

       System.out.println("\n");

}
