Assignment 3
Due: February 25, 2004
Create a Java applet that will draw figures of various sizes and colors. Place them where you
wish on the applet. Run the applet from an html file like the one below. The red circle and blue
rectangle defined in the file are only examples. You may keep them or not as you wish. But
definitely add several more figures with different sizes and colors. You can draw a square by
making the width and height equal.
import java.awt.*;
import java.applet.Applet;
// A class that draws several figures, a red circle and a blue rectangle.
public class Figures extends Applet
{
private Circle redCircle;
private Rectangle blueRectangle;
public void init ()
{
redCircle = new Circle (Color.red, 100, 100, 50);
blueRectangle = new Rectangle (Color.blue, 200, 100, 60, 40);
} // method init
public void paint (Graphics g)
{
redCircle.drawCircle (g);
blueRectangle.drawRectangle (g);
} // method paint
} // class Figures
// A class that can display a circle.
class Circle
{
private Color color;
private int x, y, diameter;
Circle (Color c, int xValue, int yValue, int d)
{
color = c;
x = xValue;
y = yValue;
diameter = d;
} // constructor
public void drawCircle (Graphics g)
{
g.setColor (color);
g.fillOval (x, y, diameter, diameter);
} // method drawCircle
} // class Circle
