When i want to get a cell value from my table (after search with filtering) and select that row and execute the returnAction()
, Exception occur.
My code:
public class BookPage_User extends JFrame implements ActionListener {
private JButton returnBookBtn;
private JTextField filterTF;
private TableRowSorter sorter;
private JTable table;
private BookJDBC bookJDBC;
private BookModel model;
public BookPage_User(String[] enterUserInfo, String userId) {
bookJDBC = new BookJDBC();
model = new BookModel(bookJDBC.getData(), bookJDBC.getColumn());
sorter = new TableRowSorter<TableModel>(model);
table = new JTable(model);
table.setRowSorter(sorter);
add(createForm(), BorderLayout.NORTH);
add(new JScrollPane(table), BorderLayout.CENTER);
RowFilter<BookModel, Object> rf = null;
rf = RowFilter.regexFilter(filterTF.getText(), 0);
sorter.setRowFilter(rf);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(850, 600);
setVisible(true);
}
public JPanel createForm() {
JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
returnBookBtn = new JButton("Return Book");
filterTF = new JTextField(10);
filterTF.getDocument().addDocumentListener(new DocumentListener() {
@Override
public void insertUpdate(DocumentEvent e) {
String key = filterTF.getText().trim();
if (key.length() == 0) sorter.setRowFilter(null);
else sorter.setRowFilter(RowFilter.regexFilter(key, 1));
}
@Override
public void removeUpdate(DocumentEvent e) {
String key = filterTF.getText().trim();
if (key.length() == 0) sorter.setRowFilter(null);
else sorter.setRowFilter(RowFilter.regexFilter(key, 1));
}
@Override
public void changedUpdate(DocumentEvent e) {
//To change body of implemented methods use File | Settings | File Templates.
}
});
returnBookBtn.addActionListener(this);
panel.add(returnBookBtn);
panel.add(filterTF);
return panel;
}
@Override
public void actionPerformed(ActionEvent e) {
if (e.getSource() == returnBookBtn) returnAction();
}
public void returnAction() {
if (table.getSelectedRow() > -1) {
int rowInTable = table.getSelectedRow();
int rowInModel = table.convertRowIndexToModel(rowInTable);
String oldStatus = String.valueOf(table.getValueAt(rowInModel, 3)); // Exception occur here!
String returnBookId = String.valueOf(table.getValueAt(rowInModel, 0));
if (oldStatus.equalsIgnoreCase("Yes")) {
model.updateBooksTableReturnAction(rowInModel);
model.deleteFromBorrowTable(returnBookId);
} else {
JOptionPane.showMessageDialog(null, "This Book Not Borrowed");
return;
}
} else JOptionPane.showMessageDialog(null, "Select a book");
}
The exception that I've got is as follows -

I am assuming(or this is actually the reason), You are actually having the issue with the following line:
String oldStatus = String.valueOf(table.getValueAt(rowInModel, 3));
JTable.getValueAt(row, col)
method will return the value of the cell (row, col)
by converting them to model-index where (row, col)
is view-index. Let use look into the source of JTable
class:
public Object getValueAt(int row, int column) {
return getModel().getValueAt(convertRowIndexToModel(row),
convertColumnIndexToModel(column));
}
So your passed (row, col)
to this function should belongs to the view, instead of model. In your context which is rowInTable
. The rowInModel
is already a model index as you got it from table.convertRowIndexToModel(rowInTable)
. By calling JTable.getValueAt(rowInModel, 3)
you are essentially trying to convert a model index to another model index resulting in computational error.
