Hi Friend,

Try the following code:

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

public class JTableDatabase{
JCheckBox check;
public static void main(String[] args) {
new JTableDatabase();
}
public JTableDatabase(){
JFrame frame = new JFrame();
JPanel panel = new JPanel();
String data[][] = {{"Name","Address"}};
String col[] = {"Name","Address"};
final DefaultTableModel model = new DefaultTableModel(data,col);
final JTable table = new JTable(model);
JScrollPane pane=new JScrollPane(table);
model.addColumn("ABC");
TableColumn includeColumn = table.getColumnModel().getColumn(2);
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/register","root";, "root");
Statement st=conn.createStatement();
final ResultSet rs=st.executeQuery("select * from data");
check=new JCheckBox("",false);
while(rs.next()){
model.insertRow(table.getRowCount(),new Object[]{rs.getString("name"),rs.getString("address")});
includeColumn.setCellEditor(new DefaultCellEditor(check));
includeColumn.setCellRenderer(new checkboxCellRender());
}
model.removeRow(0);
}
catch(Exception e){}
panel.add(pane);
frame.add(panel);
frame.setSize(500,300);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
class checkboxCellRender extends JCheckBox
implements TableCellRenderer{
public Component getTableCellRendererComponent( JTable t,Object value, boolean isSelected, boolean hasFocus,
int row, int col)
{
JCheckBox cb = new JCheckBox();
boolean sel=check.isSelected();
if(sel){
cb.setSelected(Boolean.TRUE);
}
else{
cb.setSelected(Boolean.FALSE);
