I would simply put the numbers into strings. Then reverse the string and see if it equals the original.
String originalString = "110011";
String newString = new StringBuilder(originalString ).reverse().toString();
if (originalString.equals(newString )) {
//Is a palindrome
}
Note: Consider how you want to handle leading zeros. "11" is a palindrome, but if you need 4 values then "0011" is not.
