Explanation / Answer

Hi,

I have fixed the compiletime issue. Highlighted the code chnages below.

TrafficLightPanel.java

import java.awt.Color;

import java.awt.Dimension;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JLabel;

import javax.swing.JPanel;

public class TrafficLightPanel extends JPanel{

private JButton redButton;

private JButton greenButton;

private JButton amberButton;

private JLabel buttonLable;

private JLabel lastPressendLabel;

private JLabel buttonPanel;

//Constructor set up the GUI

public TrafficLightPanel(){

redButton = new JButton("red");

greenButton = new JButton("green");

amberButton = new JButton("amber");

ButtonListener listener = new ButtonListener();

redButton.addActionListener(listener);

greenButton.addActionListener(listener);

amberButton.addActionListener(listener);

buttonLable = new JLabel("push a Button");

setSize(new Dimension(200,300));

setBackground(Color.BLUE);

//setButtonPanelSize(new Dimension(80,290));

//setButtonPanelBackground(Color.White);

add (buttonLable);

//add(buttonPanel);

setVisible(true);   

}

public static void main(String a[]) {

new TrafficLightPanel();

}

}

class ButtonListener implements ActionListener {

public void actionPerformed(ActionEvent e) {

}

}
