Write a Java program to input a number and check if it is palindrome or not

 Write a program  in Java to input a number and check if it is  palindrome or not

Palindrome : A palindrome is a word, number, phrase, or other sequence of characters which reads the same backward as forward, such as madam or racecar.

import java.util.Scanner;

public class Palin {

public static void main(String[] args) {

Scanner sc =new Scanner(System.in);

System.out.print("Enter A Number : ");

int num =sc.nextInt();

int rev=0,ldigit;

int temp=num;

while (temp!=0) {

ldigit=temp%10;

rev=rev*10+ldigit;

temp=temp/10;

}

if (num==rev) {

System.out.println(num +" is Palindrome");

} else {

System.out.println(num +" is not Palindrome");

}

}

}

 

OUTPUT

1. 

     Enter a Number : 123454321

     123454321 is Palindrome

2. 

     Enter a Number : 345232

     345232 is not Palindrome
