 int r,sum=0,temp;    

 int n=454;  

 temp=n;    

 while(n>0){    

  r=n%10;    

  sum=(sum*10)+r;    

  n=n/10;    

 }    

 if(temp==sum)    

  System.out.println("palindrome number ");    

 else    

  System.out.println("not palindrome");    

}  

}  

Answer 2

Explanation:

import java.util.*;

class palindrome

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter any number");

int n=sc.nextInt();

int d=0;

int r=1;

int temp;

while(n>0)

{

d=n%10;

r=r*10+d;

n=n/10;

}

if(r==temp)

System.out.print("Palindrome number");

else

System.out.print("Not a palindrome number");

}

}
