Answer 1

Answer:

public class Main

{

public static void main(String[] args) {

   for(int i=1;i<=10000;i++)

   {

       int rev=palindrome(i);

       if(rev==i)

       { if(rev%2==0)

         {

           System.out.print(i+",");

         }

       }

}

}

public static int palindrome(int n)

{ int rev=0;

    while(n>0)

    {

        int r=n%10;

        n=n/10;

        rev=(rev*10)+r;

    }

    return rev;

}

}

Explanation:

last number in the output is largest 4 digit even palindrome
