Java ResultSet Closed how to fix it

The problem is when I click on the Update Button to Insert Form to textfield where I can edit Appointments but when I click the UpdateButton there was An error "Result Set Closed"

try {
    int row = jTable5.getSelectedRow();
    String Table_Click = (jTable5.getModel().getValueAt(row,0).toString());
    String sql = "Select Ap.Appointment_ID,Ap.Doc_ID,(Ut.First_Name) As Doc_FirstName,Ut.Middle_Name As Doc_MiddleName,Ut.Last_Name As Doc_LastName,Ap.Department_ID,Dt.Department_Name,Ap.Patient_ID,Pr.First_Name,Pr.Middle_Name,Pr.Last_Name,Ap.SchedDate,Ap.Description,Ap.App_Date_Registered from Appointment_Table As Ap\n" +
                     "inner join User_Table As Ut on Ap.Doc_ID=Ut.ID\n" +
                     "inner join Patient_Records As Pr on Ap.Patient_ID=Pr.Patient_ID\n" +
                     "inner join Department_Table As Dt on Ap.Department_ID=Dt.Department_ID\n" +
                     "where Appointment_ID = '"+Table_Click+"'";
    pst = conn.prepareStatement(sql);
    rs = pst.executeQuery();
if (rs.next()) {
    String add0 = rs.getString("Appointment_ID");
    AppointmentID.setText(add0);
    String add1 = rs.getString("Department_Name");
    DoctorDep_Update.setSelectedItem(add1);
    String add2 = rs.getString("Doc_FirstName");
    DoctorName_Update3.setText(add2);
    ....
}

} catch(Exception e) {

JOptionPane.showMessageDialog(null, e);

} finally {

try {

rs.close();

pst.close();

} catch(Exception e) {
}

}

When I put

String add2 = rs.getString(“Doc_FirstName”);

DoctorName_Update3.setText(add2);

the error appears I think there is some mistake in my query but I cannot solve it… when I try to run it on SQlite Browser result show up

it is saying that the error is on

DoctorName_Update3.setText(add2);
