Java code to check number is palindrome or not.

import java.util.Scanner;

public class CheckPalindrome {
   
      public static void main(String args[])
    {
    Scanner ob= new Scanner(System.in);
   double k;int a,count=0;
   double r=0;
    System.out.println("Enter an integer");
    a=ob.nextInt();
    int b=a;
    while(b!=0)  //loop to count number of digits in a
    {b=b/10;
    count++;
    }
   b=a;
  for(int i=count;i>0;i--)
  {k=b%10;
  k*= Math.pow(10,i-1);
  r+=k;
  b=b/10;
  }
    
    if(a==r)
         System.out.println("The number is a palindrome");
    else
         System.out.println("The number is not a palindrome");
    }
   
   
}
