Steps to Check if a Number is Palindrome or Not

  • Take Input from the user using a scanner.
  • Reverse the number and store it to a new variable.

import java.util.Scanner;
public class PalindromeNumber {

        public static void main(String[] args) {
            Scanner sc = new Scanner(System.in);
            System.out.println("Enter the number");//Taking input from user
            int	n=sc.nextInt();
            int temp=n;
            int reverse=0;
            //loop for reversing the number.
            while(temp>0) {
                reverse=reverse*10+temp%10;
                temp=temp/10;

            }
            //checking the number is palindrome or not.
            if(n==reverse) {
                System.out.println("No is palindrome");
            }
            else {
                System.out.println("No is not palindrome");
