take a look at this code.
import javax.swing.JTable;
import javax.swing.JScrollPane;
import javax.swing.JPanel;
import javax.swing.JFrame;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class SimpleTableDemo extends JFrame implements TableModelListener {
private boolean DEBUG = true;
javax.swing.table.TableModel modela;
public SimpleTableDemo() {
super("SimpleTableDemo");
Object[][] data = {
{"Mary", "Campione",
"Snowboarding", new Integer(5), new Boolean(false)},
{"Alison", "Huml",
"Rowing", new Integer(3), new Boolean(true)},
{"Kathy", "Walrath",
"Chasing toddlers", new Integer(2), new Boolean(false)},
{"Mark", "Andrews",
"Speed reading", new Integer(20), new Boolean(true)},
{"Angela", "Lih",
"Teaching high school", new Integer(4), new Boolean(false)}
String[] columnNames = {"First Name",
"Last Name",
"Sport",
"# of Years",
"Vegetarian"};
final JTable table = new JTable(data, columnNames);
table.setPreferredScrollableViewportSize(new Dimension(500, 70));
modela = table.getModel();
modela.addTableModelListener(this);
//Create the scroll pane and add the table to it.
JScrollPane scrollPane = new JScrollPane(table);
//Add the scroll pane to this window.
getContentPane().add(scrollPane, BorderLayout.CENTER);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
public void tableChanged(TableModelEvent e){
int row = e.getFirstRow();
int column = e.getColumn();
Object firstname = modela.getValueAt(row, 0);
Object lastname = modela.getValueAt(row, 1);
Object sport = modela.getValueAt(row, 2);
Object years = modela.getValueAt(row, 3);
Object veg = modela.getValueAt(row, 4);
System.out.println();
System.out.println(firstname);
System.out.println(lastname);
System.out.println(sport);
System.out.println(years);
System.out.println(veg);
System.out.println();
public static void main(String[] args) {
SimpleTableDemo frame = new SimpleTableDemo();
frame.pack();
frame.setVisible(true);
hope this helps
