كود تعليمة count

مرحبا:الكود التالي لازم يعطيني عدد العناصر بجدول

int i=jComboBox1.getSelectedIndex();
           long y=jComboBox2.getSelectedIndex();
           try{
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               Connection c = DriverManager.getConnection("jdbc:odbc:Archive");
               Statement s = c.createStatement();
               ResultSet r1;ResultSet r2;
               int total,same, myID;

                       r1 =s.executeQuery("select count(*) from Normal_Post ");
                       total=r1.getInt("NormalPost_ID");
                       //r2 =s.executeQuery("select count (NormalPost_ID) from Normal_Post where year="+y);
                       //same=r2.getInt("NormalPost_ID");
                  // myID=total-same;
                   jTextField1.setText(Integer.toString(total));
               s.close();
               c.close();
             }
           catch(Exception ex){
             System.out.println(ex);
         }
