Help with finding digits within string

Question

Hi, I am very close (I believe) to finishing this program. Basically I need to scan the input (string) the user enters. If the input contains 2 digits then I outprint "Valid ID" if not, I outprint "Invalid ID"
please review and if possible help fix it?
Thank you.
import java.util.Scanner;
public class programTest
     public static void main(String[] args)
d     {
     String id;//id entered by user
     Scanner kb=new Scanner(System.in);//scanner utility
          System.out.println("Please enter an ID: ");
          id=kb.next();//assigns user's id to variable id
          if (id.length()>=2 && id.length()<=9)
                  for (int i=0; i<id.length(); i++)
                    if(Character.isDigit(id.charAt(i)))//if id contains 2 digits
                    System.out.println(i);
                    System.out.println("Valid ID");
          }

Answer 1

Finally! After sitting down for a few minutes and watching the show House I thought of a way to do it.
I am almost POSITIVE there is a simpler way to do this, so if you have it please repost the more "efficient" way.
Thank you very much for everyone's help!
import java.util.Scanner;
public class Test
     public static void main(String[] args)
     String id;//id entered by user
     Scanner kb=new Scanner(System.in);//scanner utility
     int digit=0;
          System.out.println("Please enter an ID: ");
          id=kb.next();//assigns user's id to variable id
          if (id.length()>=2 && id.length()<=9)
          {//if
                  for (int i=0; i<id.length(); i++)
                         if(Character.isDigit(id.charAt(i)))               
                         digit++;
                         if (digit!=2)
                         System.out.println("Invalid ID");
          }//if      
          else
               {     System.out.println("Invalid ID");     }
          if (digit==2)
          System.out.println("Valid ID");          
}
