Java Program Example on Reverse Number

Reverse Number using Java
This Java Reverse Number Example shows how to reverse a given number.

 
 public class ReverseNumber {  
     public static void main(String[] args) {  
         //original number  
         int number = 1234;  
         int reversedNumber = 0;  
         int temp = 0;  
         while(number > 0){  
             //use modulus operator to strip off the last digit  
             temp = number%10;  
             //create the reversed number  
             reversedNumber = reversedNumber * 10 + temp;  
             number = number/10;  
         }  
         //output the reversed number  
         System.out.println("Reversed Number is: " + reversedNumber);  
     }  
 }  

Output of this Number Reverse program would be
Reversed Number is: 4321
