A clean way would be to have a bRun boolean set somewhere and you could use
it like this :

boolean bRun;

public void run()
{
	while(this.bRun)
	{
		...
	}
}

public void actionPerformed(ActionEvent e)
{
	if (e.getActionCommand().equals(START_BUTTON_ACTION_COMMAND)
	{
		this.bRun = true;
		(new Thread(this)).start();
	}

	else if (e.getActionCommand().equals(STOP_BUTTON_ACTION_COMMAND)
		this.bRun = false;
}

This way, you thread will die naturally.
