A Palindrome problem

Question

i know how to solve the palindrome problem when the user inputs a string value, already solved that one, but now i'm having problems solving for when the user inputs an integer
my assigment calls for getDigits, which takes an integer as a parameter and returns an integer array containing the digits of the number.
i've got that finished
now i need to create a separate static method, call it isPalindrome, that will take an integer array as a parameter and return a boolean value of true or false indicating whether the integers in the array form a number palindrome.
so far this is what i have...
import java.util.*;
public class Palindrome
     public static void main(String[] args)
          Scanner kbd = new Scanner(System.in);
          int choice;
          do
               System.out.println("Enter a number to check if it's a palindrome:");
               choice = kbd.nextInt();
               getDigits(choice);
          }while (choice > 0);
     private static int[] getDigits(int num)
          if (num <= 0)
               System.out.println("Bad input in getDigits. Goodbye!");
               System.exit(1);
          int count=1;
          int num2 = num/10;
          while (num2 > 0)
               count++;
               num2 = num2/10;
          int[] tmp = new int[count];
          for (int i = tmp.length-1; i>=0; i--)
               tmp[i] = num%10;
               num = num/10;
          return tmp;
private static boolean isPalindrome(int[] tmp2)
          int length = num; //how do i find the length of the tmp array?
          for (int j = 0; j < length; j++)
               tmp2[j] = tmp[length - 1 - j];
}

ohh gotcha goctha
thank you sooo much for the help, i really appreciate it! just fixed my isPalindrome method
now i just have one last thing to figure out...
Pal is not being read locally... yet i use it just a few lines after i initiate it... which causes everything to be returned as positive
import java.util.*;
public class Palindrome
     public static void main(String[] args)
          Scanner kbd = new Scanner(System.in);
          int choice;
          do
               System.out.println("Enter a number to check if it's a palindrome:");
               choice = kbd.nextInt();
               int[] digitsArr = getDigits(choice);     
               boolean Pal = isPalindrome(digitsArr);
               if (Pal = true)
                    System.out.println(choice + " is a palindrome!");     
               if (Pal = false)
                    System.out.println(choice + " is NOT a palindrome");
          }while (choice > 0);
     private static int[] getDigits(int num)
          if (num <= 0)
               System.out.println("Bad input in getDigits. Goodbye!");
               System.exit(1);
          int count=1;
          int num2 = num/10;
          while (num2 > 0)
               count++;
               num2 = num2/10;
          int[] tmp = new int[count];
          for (int i = tmp.length-1; i>=0; i--)
               tmp[i] = num%10;
               num = num/10;
          return tmp;     
     private static boolean isPalindrome(int[] toCheck)
          int len = toCheck.length;
          for (int j = 0; j < len ; j++)
               if(toCheck[j] != toCheck[len - 1 - j])
                    return false;
          return true;
