Here is the code:
  ps = con.prepareStatement("select first, last from cust where ssn=?");
        int ssnint = Integer.parseInt(ssn.trim());
        ps.setInt(1, ssnint);
        ResultSet rs=ps.executeQuery();
        if ( {
                out.println("Customer already exists " + Integer.parseInt(ssn));
  do  insert (not shown)
  I get the message "customer already exists" for EVERY ssn that I tried.

Without seeing code, it's hard to say -- but I'll just guess that you're
assuming an *empty* ResultSet is a null object, and that's simply not
