No, she wants numerical palindromes.101 is a good one. As in Java 101. As in the class this is for.

I have always been fond of 666.

But seriously though, if you want to get help here, you need to show a lot more initiative than just asking a question. How do you expect us to put effort into solving your problem if you don't? Show us what you have tried, and please use the code tags. Tell us exactly what your problem is. If you don't know where to start, describe how you would do this on paper.

Hm... if you have to avoid arrays, I'd use recursion.

Google for "numerical palindrome", and you will find an algorithm to create a numerical palindrome starting from almost any given number (it works for most starting numbers).

uh, something quick

public int palindromize(int number)

{

int retnum = number;

while((number/10) !=0)

{

retnum = retnum * 10 + (number%10);

number = number/10;

}

retnum = retnum * 10 + number;

return retnum;

}
