Question

The follow functions initiate the sorter just after initializing the components in the file student.dialog
void mySettings()
//jTable1.rowSelectionAllowed();
jTable1.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
//jTable1.setFont(new Font("Helvetica", Font.PLAIN, 10));
jTable1.setModel(new StudentTableModel(jTable1,jLabel25));
// MyTableModel model = new MyTableModel(this.rw,this.cl);
sorter = new TableRowSorter(jTable1.getModel());
jTable1.setRowSorter(sorter);
//jTable1.getValueAt(rw, cl);
// System.out.println(jTable1.getColumnModel().getColumn(2));
jTable1.getSelectionModel().addListSelectionListener(
new ListSelectionListener() {
public void valueChanged(ListSelectionEvent event) {
int viewRow = jTable1.getSelectedRowCount();
//jLabel1.setText(String.valueOf(jTable1.getSelectedRowCount()));
if (viewRow < 0) {
//Selection got filtered away.
// statusText.setText("");
} else {
//int modelRow =
// jTable1.convertRowIndexToModel(viewRow);
firstName.getDocument().addDocumentListener(
new DocumentListener() {
@Override
public void changedUpdate(DocumentEvent e) {
newFilter();
@Override
public void insertUpdate(DocumentEvent e) {
newFilter();
@Override
public void removeUpdate(DocumentEvent e) {
newFilter();
lastName.getDocument().addDocumentListener(
new DocumentListener() {
@Override
public void changedUpdate(DocumentEvent e) {
newFilter();
@Override
public void insertUpdate(DocumentEvent e) {
newFilter();
@Override
public void removeUpdate(DocumentEvent e) {
newFilter();
}After this when a user select a filter and table get sorted only 10 records appear there int the jtable from which a user select just one and press the remove button on that click i have written this
int rowArr [] =jTable1.getSelectedRows();
for(int rowId:rowArr)
try
// System.out.println(sorter.convertRowIndexToModel(rowId));
sorter.getModel().fireTableRowsDeleted(jTable1.convertRowIndexToModel(rowId), jTable1.convertRowIndexToModel(rowId));
//sorter.rowsDeleted(rowId, rowId);
int stuId = Integer.valueOf(String.valueOf(jTable1.getValueAt(rowId, 0)));
int sessId= Singleton.getInstance().session_id;
conn = Singleton.getInstance().makeConnection();
query="DELETE FROM student_class WHERE student_id =? AND admClass1 AND session_id=?"; // 7
s=conn.prepareStatement(query);
s.setInt(1,stuId);
s.setInt(2,sessId);
s.execute();
}catch(Exception e)
e.printStackTrace();
}Do not think that i want multiple records to be delete i m selecting only one record but when i click on the remove button it gives me the following stack trace:

Answer 1

Use your debugger and step though to actually see what is happening, also if you have N rows and one is removed you then only have N-1 rows and any attempt to address the container with N rows will fail.
