Will this help you? Not sure if you ask that your program can take multiple numbers and test each for palindrome, but surely you will need a function like below:
public static boolean isPalindrome(int n) {
String s = Integer.toString(n);
for(int i=0; i<s.length()/2; i++) {
if (s.charAt(i) != s.charAt(s.length()-i-1)) {
return false;
}
}
return true;
}
