Question
I'm supposed to add a car image.. How can I fix my code to do that on here?
And lastly how can I add a rectangular black background around my traffic lights (so that it looks more like a traffic light)?? I still need to see the pink background of course.
my car image: car.jpg
Here is my current code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.border.*;
public class TrafficLight extends JFrame implements ActionListener {
JButton b1, b2, b3;
Signal green = new Signal(Color.green);
Signal yellow = new Signal(Color.yellow);
Signal red = new Signal(Color.red);
public TrafficLight(){
super("Traffic Light");
/* We don't need to set any layout since by default Border Layout is set */
b1 = new JButton("STOP!");
b2 = new JButton("WAIT!");
b3 = new JButton("GO!");
b1.addActionListener(this);
b2.addActionListener(this);
b3.addActionListener(this);
green.turnOn(false);
yellow.turnOn(false);
red.turnOn(true);
JPanel p1 = new JPanel(new GridLayout(3,1));
p1.add(red);
p1.add(yellow);
p1.add(green);
JPanel p2 = new JPanel(new FlowLayout());
p2.add(b1);
p2.add(b2);
p2.add(b3);
getContentPane().add(p1, BorderLayout.CENTER); /*Adding Signals at the center of Border layout */
getContentPane().add(p2, BorderLayout.SOUTH); /*Adding Signals at the bottom of Border layout */
pack();
}
public static void main(String[] args){
TrafficLight tl = new TrafficLight();
tl.setVisible(true);
}
public void actionPerformed(ActionEvent e){
if (e.getSource() == b1){
green.turnOn(false);
yellow.turnOn(false);
red.turnOn(true);
} else if (e.getSource() == b2){
yellow.turnOn(true);
green.turnOn(false);
red.turnOn(false);
} else if (e.getSource() == b3){
red.turnOn(false);
yellow.turnOn(false);
green.turnOn(true);
}
}
}
class Signal extends JPanel{
Color on;
int radius = 25;
int border = 10;
boolean change;
Signal(Color color){
on = color;
change = true;
}
public void turnOn(boolean a){
change = a;
repaint();
}
public Dimension getPreferredSize(){
int size = (radius+border)*2;
return new Dimension( size, size );
}
public void paintComponent(Graphics g){
g.setColor( Color.pink );
g.fillRect(0,0,getWidth(),getHeight());
if (change){
g.setColor( on );
} else {
g.setColor( on.darker().darker().darker() );
}
g.fillOval( border,border,2*radius,2*radius );
}
class Car{
int year;
String make;
double speed;
public Car(int y,String m,double s){
this.year = y;
this.make = m;
this.speed = s;
}
public double getSpeed(){
return this.speed;
}
public String getMake(){
return this.make;
}
public int getYear(){
return this.year;
}
public void accelerate(){
this.speed+=1;
}
}
}
Explanation / Answer
yes you can. by using this command:-
ImageIcon image = new ImageIcon("C:image.gif");
(instead of C:image.gif you must write your image location)
And You can use this for code for traffic light:-
Thank you :)
