 while(n>0){    

  r=n%10;  //getting remainder  

  sum=(sum*10)+r;    

  n=n/10;

Answer 2

Question:-

Write a program in Java to input a number and check whether it is Palindrome or not using while loop.

Program:-

import java.util.*;

class Palindrome

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

int a, b, s=0;

System.out.print("Enter a number: ");

a=sc.nextInt();

b=a;

while(b!=0)

{

s=s*10+b%10;

b/=10;

}

if(s==a)

System.out.println("Number is Palindrome.");

else

System.out.println("Number is not Palindrome.");

}

}
