Java Palindrome Program

class PalindromeExample
{
public static void main(String args[])
{
int r,sum=0,temp;
int n=454;//It is the number variable to be checked for palindrome
temp=n; 

while(n>0){
r=n%10; //getting remainder
sum=(sum*10)+r;
n=n/10;
} 

if(temp==sum) 
{
System.out.println("palindrome number ");
else
System.out.println("not palindrome");
}
}

Output :
palindrome number
