Answer 1

import java.until.*;
class prg
{
public static void main(String abc[]);
{
Scanner in= new Scanner(System.in);
int a,b,c,d=0;
System.out.println("Enter a number");
a=c=in.nextInt();
while(c>0)
{
b=c%10;
c/=10;
d=d*10+b;
}
if(a==d)
System.out.println("palindrome");
else
System.out.println("not a palindrome");
}
}

Answer 2

Answer:

import java.util.*;

class Palindrome

{

   public static void main()

   {

       Scanner sc=new Scanner(System.in);

       System.out.println("enter a number");

       int num=sc.nextInt();

       int  reversedno = 0, remainder, originalno;

       originalno = num;

       

       while( num != 0 )

       {

           remainder = num % 10;

           reversedno = reversedno * 10 + remainder;

           num  /= 10;

       }

       

       if (originalno == reversedno)

           System.out.println(originalno + " is a palindrome.");

       else

           System.out.println(originalno + " is not a palindrome.");

   }

}
