Display a Data From JTable into TextArea - swing

Question

How can i display a data from a 'specific column' of JTable when a row is selected (table.getvalue(table.getValueAt(table.getSelectedRow(),'specific column'))into a Textarea.
is there any Listener to make this work ?i mean in every selection the textarea must be updated and take the value of specific column where the row is selected .

Add a MouseListener to the table. When ever user selects the cell then just get the data and set the text to the TextField. You can see the demo by running the following code.
private void createUI() {
JFrame frame = new JFrame();
frame.setLayout(new BorderLayout());
Object[][] data = {{"a", "b"}, {"c", "d"}, {"e", "f"}};
Object[] columnNames = {"Col-1", "Col-2"};
final JTable table = new JTable(data, columnNames);
JPanel btnPnl = new JPanel(new FlowLayout(FlowLayout.LEFT));
btnPnl.add(new JLabel("Selected Value: "));
final JTextField text = new JTextField(10);
btnPnl.add(text);
table.getTableHeader().setReorderingAllowed(false);
table.addMouseListener(new MouseAdapter() {
#Override
public void mouseClicked(MouseEvent e) {
if(table.getSelectedRow() != -1 && table.getSelectedColumn() != -1) {
String selData = table.getValueAt(table.getSelectedRow(), table.getSelectedColumn()).toString();
text.setText(selData);
}
}
});
frame.add(table.getTableHeader(), BorderLayout.NORTH);
frame.add(table, BorderLayout.CENTER);
frame.add(btnPnl, BorderLayout.SOUTH);
frame.setTitle("Table to TextField Example.");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
