However when I run the code, the first row will always disappear This picture is the result I've got when I run the code

I am new to JDBC, Thank You

   String query = "select * from item where title like ?";
    String search = SearchItemText.getText();
    if (SearchItemText.getText().isEmpty()) {
        JOptionPane.showMessageDialog(null, "Search cannot leave blank");
    } else {
        ArrayList<String> item = new ArrayList<>();
        try (
                Connection con = DriverManager.getConnection(url, user, pass);
                PreparedStatement pstmt = con.prepareStatement(query);) {
            {
                pstmt.setString(1, "%" + search + "%");

                ResultSet rs = pstmt.executeQuery();
                if (rs.next() == false) {
                    JOptionPane.showMessageDialog(null, search + " is not exist, try "
                            + "switch to uppercase or lowercase");
                }
                while (rs.next()) {
                    String item_no = rs.getString("item_no");
                    String title = rs.getString("title");
                    String number_available = rs.getString("number_available");
                    item.add(item_no + "," + title + "," + number_available);
                    Object o = item_no + " " + title + " Stock = " + number_available;
                    System.out.println(o);
                    dlm.addElement(o);
                }
            }
            ItemList.setModel(dlm);
        } catch (SQLException e) {
            System.err.println(e);
        }
    }
