Basic Face Application

[adam87]

Hey, I'm currently at University and been given a task to make a simple face application that you change the colour of face and also change the size of the face. So far i've got this:

// <applet code=RedGreen1.class
// width=200 height=150></applet>

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;

public class RedGreen1 extends Applet
implements ActionListener, AdjustmentListener
{
private int diameter = 40;
private Color color = Color.red;
private Button red, green;
private Scrollbar slider;
private int sliderValue;

public void init()
{
Label sliderLabel = new Label("Size:");
add(sliderLabel);
slider = new Scrollbar(Scrollbar.HORIZONTAL,
20, 1, 0, 101);
add(slider);
slider.addAdjustmentListener(this);
sliderValue = slider.getValue();
red = new Button("Red");
add(red);
red.addActionListener(this);
green = new Button("Green");
add(green);
green.addActionListener(this);
}

public void paint(Graphics g)
{
g.setColor(color);
g.fillOval(40, 40, sliderValue, sliderValue);
g.setColor(color.black);
g.fillOval(45, 45, 5, 5);
g.fillOval(52, 45, 5, 5);
g.fillOval(50, 50, 2, 2);

}

public void actionPerformed(ActionEvent event)
{
if (event.getSource() == red)
color = Color.red;
if (event.getSource() == green)
color = Color.green;
repaint();
}

public void
adjustmentValueChanged(AdjustmentEvent e)
{
sliderValue = slider.getValue();
repaint();
}
}

There are a couple bits I am unsure about the fist is changing the deafult size of the face.

Secondly I would like the slider thange change all parts of the face and keep it in ratio.

Any help will be appreciated

Hey, I have had a go at adding the mouth but when I add it, it doesnt show up! any suggestions on how i would add a mouth?

[hardwired]

        // Mouth.
        offsetY = (int)(scale*7);
        int w = 2*offsetX;
        int h =  (int)(scale*5);
        x = faceCenter.x - offsetX;
        y = faceCenter.y + offsetY - h;
        g.fillArc(x, y, w, h, 175, 190);
