Using JTables to display data from a text file

Question

How do I display data from a .txt file into a column inside a JTable?

Answer 1

dont quite get the "vectors" part..
by the way, my program is as follows
* Damn Java ..
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
public class ScoreBoard extends JPanel {
private boolean DEBUG = false;
public ScoreBoard() {
super(new GridLayout(1,0));
String[] columnNames = {"Player's Name",
"Time Completed",
"$ Amount Earned $"};
/* Object[][] data = {
{"1",
new Integer(5), new Integer(500)},
{"2",
new Integer(5), new Integer(3200)},
{"3",
new Integer(5), new Integer(1000)},
{"4",
new Integer(5), new Integer(100)},
{"5",
new Integer(5), new Integer(200)},
final JTable table = new JTable(data, columnNames);
table.setPreferredScrollableViewportSize(new Dimension(600, 90));
if (DEBUG) {
table.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
printDebugData(table);
//Create the scroll pane and add the table to it.
JScrollPane scrollPane = new JScrollPane(table);
//Add the scroll pane to this panel.
add(scrollPane);
private void printDebugData(JTable table) {
int numRows = table.getRowCount();
int numCols = table.getColumnCount();
javax.swing.table.TableModel model = table.getModel();
System.out.println("Value of data: ");
for (int i=0; i < numRows; i++) {
System.out.print(" row " + i + ":");
for (int j=0; j < numCols; j++) {
System.out.print(" " + model.getValueAt(i, j));
System.out.println();
System.out.println("--------------------------");
* Create the GUI and show it. For thread safety,
* this method should be invoked from the
* event-dispatching thread.
private static void createAndShowGUI() {
//Make sure we have nice window decorations.
JFrame.setDefaultLookAndFeelDecorated(true);
//Create and set up the window.
JFrame frame = new JFrame("ScoreBoard");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Create and set up the content pane.
ScoreBoard newContentPane = new ScoreBoard();
newContentPane.setOpaque(true); //content panes must be opaque
frame.setContentPane(newContentPane);
//Display the window.
frame.pack();
frame.setVisible(true);
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
and i want to display the player name from a textfile.txt to the player column instead of hardcoding it like above. Thanks!
