Answer 1

import java.util.Scanner;

class PalindromeExample{  

public static void main(String args[]){  

  

  Scanner in = new Scanner(System.in);  

System.out.println("Enter a number to check if it is a palindrome");

int n=in.nextInt();

int result=checkpal(n);

if(result ==1)    

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

else    

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

}

public static int checkpal( int n)

{

int r,sum=0,temp;

//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)    

return 1;   

else    

return 0;

}
