每当我尝试获取表上的值并在 `setString` 上使用它时，我都会收到 indexOutOfBoundsException

Question

I cant get the data on my table when using setString() method it says that indexOutOfBoundsException

String upd = "update sinfo set sname = ?, course = ?, section = ?, dob = ?, address = ? where sid = ?";
String sc = course.getSelectedItem().toString();
TableModel model = sTable.getModel();
int i = sTable.getSelectedRow();

pst = conn.prepareStatement(upd);

pst.setString(1, sn.getText());
pst.setString(2, sc);
pst.setString(3, ss.getText());
pst.setString(4, db.getText());
pst.setString(5, ad.getText());
pst.setString(6, model.getValueAt(i,0).toString()); //I get the error here saying indexOutOfBoundsException: -1

pst.executeUpdate();

I already fixed it, camickr is right. Whenever I select a row on a table, the selected row will reset. And that is the cause of the error. Thank you and sorry because im new to programming and using this site😅
