Listening to JTable Events with a TableModelListener

If you want to dynamically update your table data, you can work with a TableModelListener to find out when the data changes. The interface consists of one method that tells you when the table data changes. public interface TableModelListener extends EventListener {   public void tableChanged(TableModelEvent e); } import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.event.TableModelEvent; import javax.swing.event.TableModelListener; public class TableModelListenerDemo {   public static void main(String args[]) {     final Object rowData[][] = { { "1", "one", "I" }, { "2", "two", "II" }, { "3", "three", "III" } };     final String columnNames[] = { "#", "English", "Roman" };     final JTable table = new JTable(rowData, columnNames);     JScrollPane scrollPane = new JScrollPane(table);     table.getModel().addTableModelListener(new TableModelListener() {       public void tableChanged(TableModelEvent e) {          System.out.println(e);       }     });     table.setValueAt("",0,0);     JFrame frame = new JFrame("Resizing Table");     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     frame.add(scrollPane, BorderLayout.CENTER);     frame.setSize(300, 150);     frame.setVisible(true);   } }
