You first. Let's see what you tried.

Have you gone through the JTable API and the tutorial linked from the API to discover what methods might be useful? You might also want to take a look at the DefaultTableModel API.

I have tried

public class RemoveRows{
public static void main(String[] args) {
new RemoveRows();
}

public RemoveRows(){
JFrame frame = new JFrame("Delete Rows");
JPanel panel = new JPanel();
String data[][] = {{"abc","100"},{"def","200"}};
String col[] = {"Name","code"};
final DefaultTableModel model = new DefaultTableModel(data,col);
final JTable table = new JTable(model);
Jbutton button = new Jbutton("Click to delete");
button.addEventListener(new ActionEvent(){
void action performed(Event e)
{

model.removeRow(table.getSelectedRow());
}


panel.add(table);
panel.add(button);

frame.add(panel);
frame.setSize(300,300);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

But you don't even have checkboxes in your JTable yet, not that I can see. First step would be to put boolean values into your table model, so there's some data for the checkboxes to represent.

I have tries to put new Bollean(true);

But i got the values true or false in the coloumn.

I have learnt that i need to override a method.

can anybody help me with this

For checkboxes to appear you need to override the getColumnClass in your tablemodel to return Boolean in the column you want.
Read the javax.swing.table.DefaultTableModel documentation. I know its a little confusing at first but its not that hard to understand.
