JTable: how to "synchronize" (and update) with an array ?

Question

Hello.
I am new to the Swing and I have been googling to find a solution for my problem, but I've spent too much time and found nothing. Please give me some advice.
So: I have an array of data and a JTable. The array is constantly being changed and I would like to update the JTable with every change in the array.
Thank you so much for yr help.

So here I am with an as-simple-as-possible example of my problem.
Just run it, everything is in this class.
And you'll have a table with 10 rows with 0 in every row. Every 2 seconds one line should change, but it doesn't, only if you resize the frame, or click in a cell the numbers in the cells will change.
Q: how to change it without resizing or clicking into the table ?
package MainFrame;
import java.awt.BorderLayout;
import javax.swing.JTable;
import javax.swing.WindowConstants;
import javax.swing.SwingUtilities;
import javax.swing.table.AbstractTableModel;
class NewJFrame extends javax.swing.JFrame {
     private static JTable jTable;
     public static void main(String[] args) throws Exception {
          SwingUtilities.invokeAndWait(new Runnable() {
               public void run() {
                    NewJFrame inst = new NewJFrame();
                    inst.setLocationRelativeTo(null);
                    inst.setVisible(true);
          Generator gen = new Generator(jTable);
     public NewJFrame() {
          super();
          initGUI();
     private void initGUI() {
          try {
               setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
               jTable = new JTable(new MyTableModel());
               getContentPane().add(jTable, BorderLayout.CENTER);
               pack();
               this.setSize(399, 263);
          } catch (Exception e) {
               e.printStackTrace();
class Generator extends Thread {
     private int[] array = new int[10];
     JTable table;
     public Generator(JTable table) {
          array = new int[10];
          this.table = table;
          this.start();
     public void run() {
          super.run();
          for (int i = 0; i < 10; i++) {
               array[i] = i + 200;
               table.getModel().setValueAt(i, i, 0);
               try {
                    Thread.sleep(2000);
               } catch (InterruptedException e) {
class MyTableModel extends AbstractTableModel {
     private int[] array = new int[10];
     public int getColumnCount() {
          return 1;
     public int getRowCount() {
          return array.length;
     public Object getValueAt(int arg0, int arg1) {
          return array[arg0];
     public void setValueAt(Object value, int rowIndex, int columnIndex) {
          array[rowIndex] = ((Integer) value).intValue();
}Thank you so so much my man.
