Reversing any number means changing the numbers with mirror. For example reverse of 1367 is 7631.

Palindrome number in Java : A palindrome number is a number such that if we reverse it, it will not change. For example some palindrome numbers examples are 121, 212, 12321,-454.

Java code for palindrome number-:

*import java.util.Scanner;*

*public class palindrome_number {*

* public static void main(String[] args) {*

* Scanner s=new Scanner(System.in);*

* System.err.print(“Enter the number : “);*

* int num=s.nextInt(),n=num,d=0,a;*

* while(n>0) //Loop which reverses the digits*

* {*

* a=n%10;*

* d=(d*10)+a;*

* n=n/10;*

* }*

* System.out.println(“Reverse of “+num+” is “+d);*

* if(num==d) //condition that checks for palindrome number*

* System.out.println(“Since “+num+” and “+d+” is same so “+num+” is a palindrome number.”);*

* else*

* System.out.println(“Since “+num+” and “+d+” is not same so “+num+” is not a palindrome number.”);*

* }*

*}*
