Variable name of Swing component in Netbeans

I have an application that is currently using over 200 buttons, each of which returns the String of their variable name. Is there any way to do this? Setting the name property for each of these would be far too time consuming.

use JButton#putClientProperty for identifying concrete JButton

buttons[i][j].putClientProperty("column", i);
buttons[i][j].putClientProperty("row", j);
buttons[i][j].addActionListener(new MyActionListener());

and get from ActionListener (for example)

public class MyActionListener implements ActionListener {

    @Override
    public void actionPerformed(ActionEvent e) {
        JButton btn = (JButton) e.getSource();
        System.out.println("clicked column " + btn.getClientProperty("column")
                + ", row " + btn.getClientProperty("row"));
}

Use a collection of buttons:

ActionListener theActionListener = new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println(((JButton) e.getSource()).getName());
    }
};

List<JButton> buttons = new ArrayList<JButton>();
for (int i = 0; i < 200; i++) {
    JButton button = new JButton("Button " + (i + 1));
    button.setName("Button " + (i + 1));
    button.addActionListener(theActionListener);
    buttons.add(button);
}
