Hi , 

Please compare it with this code.

public class AccountProcessor {
  @future
  public static void countContacts(List<Id> accountIds) {
    List<Account> accounts = [Select Id, Name from Account Where Id IN :accountIds];
    // process account records to do awesome stuff
    List<Contact> con = [select id from contact where AccountId in :accounts];
        for(Account a : accounts){
            a.Number_Of_Contacts__c=con.size();
        }
  }
}
