multiple button listeners
I got the button for one to work however I am a bit stumped on how to get the other buttons. Can someone lead me in the right direction as to how to create a button event listener for the other buttons? I want the text to display in the same JLabel.
JButton one =new JButton ("1");
one.addActionListener(new ButtonListener());
JButton two =new JButton ("2");
two.addActionListener(new ButtonListener());
JButton three =new JButton ("3");
JButton four =new JButton ("4");
JButton five =new JButton ("5");
JButton six =new JButton ("6");
JButton seven =new JButton ("7");
JButton eight =new JButton ("8");
JButton nine =new JButton ("9");
JButton asterisk =new JButton ("*");
JButton zero =new JButton ("0");
JButton sharp =new JButton ("#");
add(one);
add(two);
add(three);
add(four);
add(five);
add(six);
add(seven);
add(eight);
add(nine);
add(asterisk);
add(zero);
add(sharp);
}

{
publicvoid actionPerformed(ActionEvent event)
{
display.setText("1");
}
}
