Hi Friend,

Try the following code:

import java.awt.*;
import java.sql.*;
import java.util.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;

public class CheckBoxAction {

  private static String des = "Deselected";
  private static String sel = "Selected";
  public static void main(String args[]) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JCheckBox checkBox = new JCheckBox(des);

    ActionListener actionListener = new ActionListener() {
      public void actionPerformed(ActionEvent actionEvent) {
        Vector columnNames = new Vector();
        Vector data = new Vector();
        AbstractButton abstractButton = (AbstractButton)actionEvent.getSource();
        boolean selected = abstractButton.getModel().isSelected();
        String newLabel = (selected ? sel : des);
        abstractButton.setText(newLabel);
      if(newLabel.equals("Selected")){
      try {
      Class.forName("com.mysql.jdbc.Driver");
      Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
      Statement st = con.createStatement();
      ResultSet rs= st.executeQuery("Select * from employee");
      ResultSetMetaData md = rs.getMetaData();
      int columns = md.getColumnCount();
      for (int i = 1; i <= columns; i++) {
      columnNames.addElement( md.getColumnName(i) );
      }
      while (rs.next()) {
      Vector row = new Vector(columns);
      for (int i = 1; i <= columns; i++) {
      row.addElement( rs.getObject(i) );
      }
      data.addElement( row );
        }
      }
      catch(Exception e){}
      JTable table = new JTable(data, columnNames);
      JScrollPane pane = new JScrollPane(table);
      JFrame f=new JFrame();
      f.add(pane);
      f.setVisible(true);
      f.pack();
      }
      }
    };
   checkBox.addActionListener(actionListener);
   checkBox.setMnemonic(KeyEvent.VK_S);
   Container contentPane = frame.getContentPane();
   contentPane.add(checkBox, BorderLayout.NORTH);
   frame.setSize(300, 100);
   frame.setVisible(true);
  }
}

Thanks
