How to reverse the given number

 We are going to see how to reverse the number is Java.

Suppose We have number 24586 so reverse of this number will be 68542.

To reverse the number we are going to use following logic.

1. Divide the number by 10 to find remainder using modulus operator(%) .

2. Define reverse number variable and initialize 0 value

3. Multiply reverse number by 10 and add remainder to it.

4.Divide the number by 10.

Let's see Java code for this Problem.

1. public class ReverseNumber {  
2. public static void main(String[] args)  {  
3. int number = 24586, reverse = 0;  
4. while(number != 0) {  
5. int remainder = number % 10;  
6. reverse = reverse * 10 + remainder;  
7. number = number/10;  
8. }  
9. System.out.println("The reverse of the given number is: " + reverse);  
10. }  
11. }
